Halloween (1978), directed by John Carpenter, is a classic horror film that revolutionized the slasher genre and remains one of the most iconic horror movies of all time. The story follows Michael Myers, a psychotic killer who escapes from a mental institution and returns to his hometown to wreak havoc on Halloween night.

At its core, Halloween delves into themes of fear, evil, and survival. Michael Myers is not given a clear motive for his murders, which adds to his terrifying persona—he is portrayed as a force of pure evil, almost inhuman in his inability to be reasoned with.

This lack of reasoning or explanation makes him unpredictable, leaving viewers with a sense of dread that evil can emerge from anywhere without reason or warning.
