Psycho
When larcenous real estate clerk Marion Crane goes on the lam with a wad of cash and hopes of starting a new life, she ends up at the notorious Bates Motel, where manager Norman Bates cares for his housebound mother.
Psycho is primarily positioned as a psychological horror/thriller with fear, dread, and iconic horror imagery (shower murder, Norman Bates). The crime/mystery elements exist but are secondary to the horror-driven experience.
Best for viewers looking for a scary, atmosphere-heavy, psychological and low-gore horror movie.
