Halloween
Fifteen years after murdering his sister on Halloween Night 1963, Michael Myers escapes from a mental hospital and returns to the small town of Haddonfield, Illinois to kill again.
Halloween (1978) is a foundational horror/slasher film in which fear, suspense, and the threat of Michael Myers drive the entire viewing experience. It is widely described and experienced as horror first; removing horror would fundamentally alter the film's identity.
Best for viewers looking for a very scary, high-tension, atmosphere-heavy, psychological and slow-burning horror movie.
