Hey there everyone! Welcome back to Movie Soapbox, the little corner of the internet that only you and I and that guy sleeping in the corner over there know about. This is the place where we find underappreciated indie films and we make sense of them. Today? We are doing a full theoretical autopsy on The Backrooms, a film so precisely, stubbornly ambiguous that its angriest critics and its loudest defenders are essentially describing two completely different movies, and both of them are right, and that is not an accident of confused filmmaking, that is a twenty-year-old kid from the internet building a trap and watching the entire discourse walk into it.
Before we go any further, understand that from this sentence forward I am going to describe, in full detail, who dies, how they die, what the ending means, and why the last shot is the most quietly devastating image in an indie horror film this decade. If you have not watched the film, go watch the film, then come back. I will be here. I am always here.
Good. Now let’s get into it.
The Making of the Backrooms Movie and Series
Kane Parsons built this film around a single deliberate hole, and he has said publicly the one reading he wanted to kill is the lazy “it was all a dream” cop-out. Everything else? He left the door open. And into that open door, the internet has poured roughly a thousand competing theories, organized into roughly five positions that matter. What I want to do here is take each one seriously, take it all the way down to its logical floor, lay out the strongest case for it, name the place where it buckles, and then tell you exactly where I land and why.
I also want to tell you something the discourse has mostly skipped past, which is what it means that this film exists at all in the shape it exists.
Because here is the thing you have to hold in your head while you read every word below: Kane Parsons made a YouTube series, built an audience of millions on a shoestring and a mythological architecture that rivals anything a writers’ room with actual money has produced in the last five years, and then turned that into a feature film that is genuinely, structurally ambitious. He did not get a studio note that said “make the monster’s origin clearer.” He did not have twelve VPs in a room demanding a rulebook for the backrooms and a cleaner third act and a sequel hook on the last frame. You can tell when a film has survived that particular gauntlet because it comes out the other side with its corners sanded off and its ambiguity replaced by exposition, and The Backrooms has not had its corners sanded. It is still sharp everywhere you touch it. That sharpness is what we are here to discuss. But never forget it is also evidence of something that doesn’t happen often, a filmmaker who got to keep his hole in the center of the story.
Now. The theories. Arranged on a spectrum from most literal to most psychological, because that tension, literal versus interior, is the actual argument the film is having with itself.
And one more thing before we descend: these five are not strictly mutually exclusive. The single most impressive architectural achievement of this film is that it actively supports more than one of them simultaneously. That is not a flaw. That is the design.
Backrooms Movie Theory 1: The Literal Reading
The thesis is simple. There is no metaphor to decode. The backrooms is a real anomalous dimension, a physical infinite space cracked open by Async Research Institute through their threshold technology, a spinoff of MRI research that went somewhere it had no business going. It copies and degrades the real world. It is leaking into reality through null zones. By the final act it is spreading. The monster is a real monster. Clark really died in there. Mary really got caught. Nobody is hallucinating anything.
This reading has the easiest job, because the film shoots its supernatural apparatus as cold, concrete fact. The cold open gives you a researcher, alone on tape dated June 19, 1990, hunted and killed by the giant, that footage being reviewed by people in white coats. That entire sequence happens before Clark exists in the story. It is not filtered through anyone’s psychology. It just happened. And then Clark later physically finds that researcher’s bag, with the tapes, the floppy disks, the ID badge. The dead man was real. His stuff is real. A dimension does not generate a dead man’s ID badge out of anyone’s subconscious. That detail is doing a lot of load-bearing work and the literal reading is the one theory that doesn’t have to strain against it.
Then there is Async itself, rendered with bureaucratic specificity: CCTV feeds, hazmat capture teams, gas traps disguised as multilingual greeter standees, a brain scan, a facility on the other side of a portal they physically walk Mary through. Phil doesn’t speak in riddles. He confesses. The company used to make MRI machines. Now it does this. He goes in himself. And within his closing ramble he admits doors are opening everywhere and nobody knows why.
For anyone who followed Kane’s YouTube series, the lore clicks cleanly: Async Research Institute, Project KV31, the Complex, the threshold. The melted fused-chairs furniture and the Voyager-golden-record standee greeting visitors in fifty languages aren’t dream logic, they’re artifacts of a place that physically builds and copies matter. The dates even line up with the series timeline.
Where the literal reading strains: if the place is purely, neutrally real and indifferent to its visitors, why is it so specifically, personally shaped by Clark? The monster is his store mascot, grown huge and given teeth. The murals are in his handwriting. His store gets recreated room for room. A truly indifferent dimension does not keep coughing up one man’s psychology. The literal reading has to wave its hand at an enormous amount of personal specificity, and the moment it does, it has already conceded ground to Theory 3.
What it says the movie is about: human institutions poking holes in reality they have no business poking, and getting people eaten for it. Cosmic horror with a corporate logo and a grant application on file.
Backrooms Theory 2: The Capitalism Reading
Still mostly literal, but it argues you have been watching the wrong threat the entire time. The real horror of The Backrooms is not the giant in the pirate hat. The real horror is the institution that found an infinite dimension and immediately started asking how to own it. Async treats the backrooms as free real estate and treats the people lost inside it as inventory. The monster is the misdirection. The men in the white coats are the antagonists.
Watch how the film brackets itself. It opens on Mary’s childhood home being demolished to build a development tower, memory and history and home all liquidated so something more profitable can rise. It closes on a corporation calmly deciding the fate of a traumatized survivor it now regards as a data point. That is a frame the film is consciously building around everything in between. Phil’s quietly monstrous line, “I’m convinced nothing in our lifetime, or in all of recorded history, means more than this,” is the voice of a man who has stopped counting the human cost because the opportunity is too enormous. And then: “that’s not up to me.” That is diffused responsibility, the org-chart dissolve of accountability that every large institution runs on. Nobody is in charge of the harm. The harm just keeps accruing.
The greeter standees aren’t welcoming anyone. They’re harvesting traps. Async isn’t trying to rescue the people inside. It’s trying to catch the merchandise. And the series lore amplifies this: Async’s stated ambition is to colonize the backrooms as infinite housing and storage, a solution to overpopulation, packaged and sold. Even Clark lands as a grace note to the thesis, a small failing capitalist (a furniture store called the Ottoman Empire, empire, consumption, a throne that literally breaks under him) who gets devoured while big capital wins and expands.
Where it strains: the film spends the overwhelming majority of its runtime inside Clark and Mary’s interior lives, not inside anyone’s boardroom. The corporate apparatus is powerful but it is a frame, it shows up at the edges, at the opening and the close. This reading is most convincing as the political atmosphere the film breathes, less so as the thing the film is fundamentally doing with its two lead characters.
What it says the movie is about: that the scariest force on earth is not supernatural, it is an institution that has decided your suffering is an acceptable line item in a budget someone else approved.
Backrooms Theory 3: The Hybrid Reading
This is the true center of the spectrum, and in my judgment the most textually loaded reading on the entire list. The backrooms is both a real dimension and a psychic mirror. Async genuinely found it, it physically exists, but it builds and rebuilds itself out of the memories and minds of whoever is near it. Clark, the failed architect, is literally drafting impossible architecture out of his own head. The place “remembers” people and renders them back as slowly degrading copies. Real and personal, at the same time, nested inside each other.
The single most important clue is scrawled on a mural Mary finds: “The floor plan changed again. I don’t know who signed the plans, but the handwriting looks like mine.” That is the film telling you in plain language that the space is being authored, and that the author is one of its prisoners. Clark spent his whole life wanting to be an architect and failing. In the backrooms, he finally gets to design. He draws the maps. The floor plan obeys him.
Then look at the monster. Captain Clark isn’t a random entity. It is a swollen, deformed version of Clark’s own furniture-store mascot persona, the pirate-sultan he costumes himself as to sell ottomans. His buried ego and shame, given scale and teeth. And Clark almost narrates the mechanism directly at the dinner table: “This place builds them. Actually, more like it remembers them. And the more times it remembers something, the less it does.” That is not how a neutral physical dimension works. That is how memory works. That is how grief works, every recall degrades the copy a little further from the original.
The geography clinches it. When Clark moves through the backrooms it is the yellow-office-maze of his world. When Mary makes her run for the exit her stretch of the place looks different, more domestic, more suburban, more like her memories. Different minds, different rooms. The backrooms isn’t one fixed map. It’s a mirror that reshapes itself around whoever’s holding it.
Where it strains: it is the most satisfying theory and also the least falsifiable, which should make you at least a little suspicious of how good it feels. A reading that can absorb any detail you throw at it has stopped being a theory and started being a religion. And it rests on a mechanism, minds physically sculpting a real place, that the film strongly implies and never once confirms out loud. It is a gorgeous inference. Emphasis on inference.
What it says the movie is about: the spaces we get lost in are the ones we built ourselves, out of the parts of us we refused to look at directly.
Backrooms Theory 4: The Trauma-Allegory Reading
Now we cross into firmly psychological territory. Under this reading the backrooms isn’t really a place at all. It is a metaphor the movie renders in three dimensions. The whole film is a psychodrama about trauma loops, avoidance, and accountability. Clark and Mary are deliberate mirror images of two ways of being broken. Captain Clark is Clark’s rage and avoidance given monstrous form. He merges with the backrooms at the precise moment he refuses accountability for his own life. Mary survives only by confronting, and then weaponizing, her own trauma.
The thesis is spoken aloud in the very first scene, before you even know it is a therapy session: we all have our loops, our habits, the behaviors that keep us walking in circles. The entire film is framed inside a therapist-client relationship. That is not a coincidence you decode at the end. It is the lens bolted onto the camera from frame one.
Every major image maps to interior life. Clark is a man so stuck he is literally living inside his own failing business, sleeping on a display bed in an empty showroom, a liminal space before he ever falls through a wall. The window-and-door motif saturates everything: Mary’s self-help book is called The Window Within; her mother papered the windows over; Clark’s farewell is “I opened the window, I won’t be coming back.” Windows and doors are thresholds between the self you hide in and the world you are afraid of, and this film is obsessed with thresholds. Even Async’s origin as an MRI company lands here: an MRI is a machine that maps the inside of your head.
The dinner scene is the allegory’s thesis statement. Mary finally drops what the profession calls unconditional positive regard and tells Clark the truth: “Nothing is ever your fault. You blame your brain. You ARE your brain.” Clark’s response is the disease confirming itself. He doesn’t want to change. He likes it here. “It’s just the way we’re wired.” He chooses the loop. So the loop, in the shape of his own monstrous mascot, picks him up and eats him. Meanwhile Mary defeats that same manifestation using the concrete handprint, the physical relic of her own childhood trauma, turned into a weapon. That is not horror logic. That is therapy, dramatized.
Where it strains: if it is pure metaphor, you have to explain away a great deal of stubbornly concrete machinery. The researcher on the tape dies before Clark exists. The hazmat teams, the gas traps, the portal, the brain scan, all of it operates independently of anyone’s psyche. A clean allegory reading has to demote that entire apparatus to mood lighting, and Kane films it far too solidly for that to sit comfortably.
What it says the movie is about: that the hardest room to escape is the one your own avoidance built, and that “it’s just how I’m wired” is the sentence that locks the door from the inside.
Backrooms Theory 5: The “It’s All Mary” Reading
The far end of the spectrum, and the boldest swing on the board. The entire descent is Mary’s own psychological break. She, not Clark, is the one who ends up institutionalized, exactly as her mother was before her. Clark, the backrooms, the monster, even Async: distortions and projections of Mary’s deepest terror, which is that she is doomed to repeat her mother’s fate, that she cannot save anyone, and that she cannot save herself. The final still-life Mary frozen in the interview room is the plain truth. She never got out because she was never out to begin with.
Of the two leads, Mary is the one carrying the psychiatric freight. The institutionalized mother. The medication she ducks into side rooms to take. The childhood in a sealed home with papered-over windows, raised by a parent who believed monsters were “all over the place.” A lifelong fixation on windows and doors. If anyone in this film is a candidate for a dissociative break, it is not the furniture salesman. It is his therapist, who has spent her entire career trying to fix broken people because she could never fix the broken person who raised her.
Read the back half through that lens and it reorganizes. Clark becomes the patient she couldn’t save, a stand-in for the mother she couldn’t save. The monster becomes her terror of inheriting her mother’s madness. The backrooms becomes the sealed, windowless home of her childhood, infinitely extended. And the ending is the tell: the film’s final horror is of a woman trapped alone in a room she is not allowed to leave, which is Mary’s specific childhood trauma, not Clark’s. The Async interview room is shot like a cell, the framing slowly drowns her in backrooms-yellow, and her final expression is a small, knowing smile, the smile of someone who has just understood exactly where she actually is.
Where it strains: it strands the cold open badly. That researcher dies on a recovered tape watched by white coats before Mary is anywhere near the plot, and Clark later finds the man’s physical bag. If the whole film is her projection, who is the dead man and where did his ID badge come from? This reading also flirts dangerously with the one ending Kane explicitly killed, and only survives if you frame it precisely as dissociation distorting real events rather than fantasy invented from nothing. It is the most provocative theory on this list and the one that demands the most squinting to hold together.
What it says the movie is about: that the deepest fear is not a monster in the dark. It is becoming your mother, alone in the sealed room you swore you would escape.
Can All These Backroom Theories Be True At Once?
Run two or three of these simultaneously and nothing breaks. The backrooms can be a literally real dimension that a corporation is criminally exploiting and that shapes itself from the minds of the people lost inside it and that therefore functions as a perfect externalization of unresolved trauma. All four of those can be true in the same frame. Kane built a literal box and a psychological box and nested them inside each other so cleanly you cannot pry them apart, which is exactly why the viewers who showed up for a monster rulebook left so angry. There is no rulebook. There is a mirror with a monster living in it.
Only Theory 5 is genuinely greedy. It wants to be the whole answer and demote everything else to delusion, and that is where it cracks against the cold open. But even Theory 5 earns its place, because it is the logical endpoint of taking the psychological reading as far as it can possibly go, and the film flirts with it hard enough that dismissing it entirely is its own kind of bad faith.
The Theory Upon Which Moviesoapbox Lands
After sitting with this film longer than a reasonable person probably should, the reading I keep returning to is Theory 3. The hybrid. The backrooms is real, and it is made of us.
I plant my flag here because it is the only theory that does not have to throw anything away. The literal reading has to ignore why the place is so personally Clark-shaped. The capitalism reading has to ignore the interior character study that is plainly the film’s emotional core. The pure-allegory reading has to ignore the researcher’s corpse on the tape. The all-Mary reading has to ignore that same corpse twice as hard. The hybrid swallows all of it whole: the place is physically real, so the tape, the bag, the hazmat teams, the portal all stand, and it sculpts itself from the minds of its prisoners, so the handwriting on the murals, the pirate-monster, the divergent geographies, and the degrading copies all make sense. The mural says it out loud, the handwriting looks like mine, and I have learned to trust a film when it tells you what it is in its own words.
Under the hybrid reading, the still-life Mary in that final room is the worst of every world simultaneously: literally trapped, psychologically consumed, and degrading with every recall. Clark wanted to be an architect his whole life and never built a single thing that lasted. In the end the only structure he ever completed was the prison that ate him, drafted in his own handwriting, out of his own refusal to change. The backrooms is real. And we are the ones who keep building it.
Kane Parsons is twenty years old. A studio with a committee and a greenlight process and a test-screening apparatus would have taken this thing and sanded every sharp edge off it until it was safe and forgettable and nobody would be writing theory posts about it at one in the morning. He did not let that happen. Pay attention to what he does next.
That’s all for today, everyone. Thanks for spending some time in this little corner of the internet with us. We’ll see you on the next one.
