The first achievement of Backrooms is that the rooms still feel wrong after years of internet familiarity.
The yellow walls, damp carpet, humming fluorescent lights, and empty office geometry have been copied into games, videos, memes, and endless variations. Kane Parsons, who expanded the concept through his YouTube series while still a teenager, understands that recognition is not enough. The film has to make a space the audience thinks it knows become unstable again.
It does. The opening moves through the maze with the degraded immediacy of recovered footage. Corridors repeat with slight differences. Furniture appears where it has no practical use. A doorway seems too small, a hall extends too far, and an ordinary object becomes frightening because it has been placed by something that understands the human world imperfectly.
Parsons' feature follows Clark, played by Chiwetel Ejiofor, the owner of a failing furniture showroom. His marriage is collapsing, he is drinking too much, and the store has become both his workplace and a place to hide from the rest of his life. When a strange opening appears below the building, Clark enters it with the misplaced confidence of a man already accustomed to avoiding the obvious danger in front of him.
His therapist, Dr. Mary Kline, is played by Renate Reinsve. Mary has her own history of grief and unstable memory, and the film gradually connects her past to a space that appears to build itself from distorted versions of places its visitors once knew. Clark recruits employees Bobby and Kat to document what he has found, turning curiosity into an experiment none of them understands.
The human story gives Parsons a way to expand an abstract internet myth into a feature. It also creates the film's most persistent weakness. Clark and Mary arrive carrying enough trauma to power several horror movies, but their histories can feel like explanations attached to images that were more frightening before they had a psychological purpose.
Ejiofor gives Clark a convincing mixture of shame, stubbornness, and fascination. He is not a fearless explorer. He keeps moving because the Backrooms offer a physical problem he can confront instead of the personal ones waiting above ground. Reinsve is quieter and more elusive. Mary studies the maze as a therapist until the environment begins studying her back.
The Backrooms are most frightening when they seem to remember the characters incorrectly.
The production design is exceptional. Much of the impossible environment was constructed physically, and that choice changes how the actors occupy it. Walls can be touched. Carpets compress under feet. Light bounces from real surfaces, producing a sickly flatness that computer-generated spaces often imitate without fully capturing.
Danny Vermette's sets do not depend on constant transformation. The dread comes from patient errors. A stop sign sits in a place where no traffic could exist. Mannequins appear to have been arranged by an intelligence rehearsing the idea of a store. Pieces of Clark's showroom and Mary's memories are reproduced without the context that once made them ordinary.
Jeremy Cox photographs the spaces with wide lenses that make distance difficult to judge. The camera can turn a tight passage into an enormous void, then make a large room feel as though its walls are moving inward. Parsons alternates controlled compositions with rough analog footage, connecting the feature to his original videos without allowing the entire film to become a found-footage exercise.
The sound is even more important. The fluorescent hum is not background noise. It becomes a pressure that follows the characters from room to room. Parsons and Edo Van Breemen build the score around low frequencies, mechanical drones, and sounds whose sources remain just outside the frame. Silence rarely feels empty. It feels occupied.
Backrooms is not especially dependent on gore. Its strongest scares come from delay and uncertainty. The audience sees a dark opening long before it knows whether anything will emerge. A figure may be a person, a stain, or a failure in the image. Parsons understands that the internet mythology became frightening because it offered almost no rules.
The movie weakens whenever it tries to provide those rules. Scientists, experiments, memory, and observation are introduced as possible explanations, but the film does not develop them into a coherent system. That ambiguity is partly intentional. Still, there is a difference between mystery and narrative material that has been left incomplete.
The middle section also repeats the same dramatic rhythm. A character enters a new space, notices something familiar in the wrong context, hears a sound, and moves deeper. Parsons keeps finding strong images, but the story begins feeling like a series of levels after the initial shock has faded.
The supporting characters suffer most. Finn Bennett and Lukita Maxwell bring nervous energy to Bobby and Kat, yet both are defined primarily by their relationship to Clark's discovery. Mark Duplass and Avan Jogia contribute to the wider mystery, but the film's most compelling character remains the architecture.
That is not necessarily a failure. Horror has always allowed a house, hotel, cave, or spaceship to become more memorable than the people trapped inside it. The Backrooms are a worthy addition to that tradition because they turn the blandest spaces of modern life into something cosmically indifferent.
Parsons is only twenty, and the confidence of the filmmaking is difficult to ignore. He does not treat online horror as raw material that needs to be made respectable by Hollywood. He preserves its anonymous images, incomplete evidence, and sense that the viewer has found something not intended for them.
Backrooms is most effective when it stops trying to become a conventional grief drama and allows the maze to remain unknowable. Its characters want the rooms to explain what they have lost. The rooms can only reproduce the shape of that loss, badly and forever.
