A masterpiece of experiential filmmaking that mines palm-sweating anticipation from what’s lurking around the next corner, director Kane Parsons’ “Backrooms” is an ambiguous yet utterly engrossing horror film for those willing to tune into its otherworldly frequency.

The film is based on 20-year-old Parsons’ YouTube series of the same name, which was inspired by the online liminal space “creepypasta” post on 4Chan from 2019. This newest iteration takes place in 1990 and focuses on Clark (Chiwetel Ejiofor), a failed-architect-turned-furniture-store-owner and alcoholic struggling after a recent divorce.

His ex-wife got the house, so Clark has taken up residence at the store. He’s seemingly resigned to a sad life running a defunct business and making embarrassing TV commercials where he’s dressed up like a pirate. 

He regularly has sessions with his therapist and self-help-book-author Mary (Renate Reinsve), who encourages Clark to reflect on his actions and break obsessive thought patterns. Mary is also a lonely soul who’s processing her own grief from a troubled childhood. She often zones out as haunted memories come flooding back.

Clark notices some strange electrical issues at the store, which eventually leads him to the basement where he finds a hidden entrance to the titular Backrooms — an alternate dimension residing in the uncomfortably uncanny valley. 

Claustrophobic, labyrinthine hallways and office spaces stretch on endlessly, enclosed by walls painted sickly yellow, lit with fluorescent lights, and littered with jumbled piles of furniture like some twisted contemporary art exhibit made by glitched-out AI software. A strange presence also stalks the premises that clearly doesn’t take kindly to visitors. 

Clark, and by extension us as viewers, are immediately thrown off kilter, but Clark becomes fascinated with this alternate universe and makes it his goal to unearth its mysteries.

Suffice it to say, dangers abound. Clark (and eventually Mary) find themselves way over their heads, becoming trapped in a place that can easily lead its inhabitants into spirals of insanity.

It might not have the most elegantly told story, but “Backrooms” is a relentlessly disorienting film, rich in oppressive atmosphere and dark absurdity, that prides itself on putting viewers in the shoes of its characters and letting the nightmarish world speak for itself.

Familiarity with Parsons’ web series isn’t needed to appreciate this film — above all else, “Backrooms” is a vibe, so stylistically assured that it conjures a universal, intoxicating sense of uneasiness.

Through a mixture of “found footage” camerawork and shots that keep us in lockstep with the characters, Parsons lets us feel the winding unknown and the relentless pressure of being chased through an unfamiliar environment without a clear exit. Although the camera generally adopts an omniscient viewpoint, we don’t jump ahead of the characters; we witness each new sight along with them.

And although Parsons does dole out some (rather cliché) themes, he keeps specific explanations vague, emphasizing the fact that this hidden world cannot be reasoned with. 

This approach, not unlike 2023’s horrifying “Skinamarink” (also made by a YouTuber turned feature film director), will prove alienating for viewers seeking a traditional narrative or characters that are easy to rally behind. 

The always reliable Ejiofor and Reinsve bring pathos and intensity to dialogue that rings intermittently too obvious and repetitive. Mary’s constant referencing of behavioral loops is an on-the-nose metaphor here, but the way Parsons brings in the existential weight of consumerism and the false promises of the American Dream are compelling threads left slightly underdeveloped.

The world and the filmmaking itself are the real stars of the show here, though — difficult to describe but viscerally felt: scenes patiently and deliberately build suspense before exploding in edge-of-your-seat set-pieces that cinematographer Jeremy Cox frames with frantic energy.

Parsons and Edo Van Breeman’s music is ingeniously woven into each sequence, feeling inextricably linked to the backrooms themselves in its rumbling, alien-like rhythms.

Sure, the film’s more traditional narrative elements feel undercooked, partly due to a rushed passage of time that feels at odds with the more deliberate approach Parsons takes in-the-moment. “Backrooms” shines in its unknowability and stumbles in the few moments when it panders to the masses, not committing to the bit quite as much as its forbears. 

Still, the feelings it conjures are indelible and specific — best experienced in a theater for maximum immersion. I can’t wait to dive back into “Backrooms” time and time again, and no, boomers, that’s not just because I’m Gen-Z.
