Repulsion is an alarming and compelling psychological thriller that presents an unsettling exploration of a woman's descent into madness. Polanski masterfully creates an atmosphere of claustrophobic dread. What sets this film apart is its bold decision to centre the narrative on a female protagonist who, in a rare move for the genre, is the killer rather than the victim. The film's chilling portrayal of isolation and paranoia lingers long after the credits roll, making it an unforgettable entry in psychological horror.
