Repulsion
Beautiful young manicurist Carole suffers from androphobia (the pathological fear of interaction with men). When her sister and roommate, Helen, leaves their London flat to go on an Italian holiday with her married boyfriend, Carole withdraws into her apartment. She begins to experience frightful hallucinations, her fear gradually mutating into madness.
Repulsion is widely recognized as a psychological horror whose core identity is fear, paranoia, and sensory-disturbance. The experience hinges on dread, hallucinations, and a claustrophobic atmosphere; removing horror would fundamentally alter the film's essential experience. It is not primarily a crime drama or thriller, but a horror-centric psychological study.
Best for viewers looking for a scary, atmosphere-heavy, psychological, slow-burning and low-gore horror movie.
