Horror films aim to elicit emotions of fear, disgust, and horror in viewers through disturbing and macabre scenes involving the supernatural, gore, and jump scares. They often overlap with fantasy, science fiction, and thriller genres. Common horror elements include ghosts, torture, demons, cursed houses, and serial killers. While early horror films drew from Gothic literature, modern horrors continue to exploit classic monsters and push boundaries of explicit content. Highest rated classics include Psycho, The Shining, and The Exorcist, while lowest rated films are often considered so bad they're funny, like Manos: The Hands of Fate.
