Rosemary's Baby

Roman Polanski's Rosemary's Baby is the most psychologically suffocating horror film ever made. Mia Farrow delivers a performance of such vulnerability and growing terror that the audience feels trapped alongside her. The film's genius is its ambiguity — for most of its runtime, you cannot be certain whether Rosemary is the victim of a satanic conspiracy or simply a woman experiencing paranoid delusions during a difficult pregnancy. Polanski keeps you in her perspective, and the claustrophobia of the Bramford apartment becomes unbearable. The ending — where Rosemary accepts what has been done to her — is one of the most disturbing and debated conclusions in horror history.
