“Backrooms” (** out of four) was an over-the-top and cerebral exercise in psychological horror about an alcoholic furniture store owner (Chiwitel Ejiofor) who disappears into another dimension of reality found in the basement of his store and his determined psychiatrist (Renate Reinsve) ventures in to go find him but soon finds that her own mental and psychological state may be in peril. Some undeniably eerie moments are obscured by film’s pretentious tone and cold-hearted unpleasantness. Yet another film all-too-obviously inspired by “The Shining” and various other early works by Kubrick and Cronenberg and cannot hold a candle to either.
