A "slasher" is a subgenre of horror films that typically features a killer stalking and murdering a group of people, often teenagers. These movies often include graphic violence, suspenseful music, and a final girl—a character who survives to confront the killer. Iconic examples of slasher films include Halloween, A Nightmare on Elm Street, and Friday the 13th. The slasher genre emerged in the late 1970s and gained popularity in the 1980s. It often explores themes of morality, fear, and the consequences of reckless behavior. The killers in these films, such as Michael Myers and Jason Voorhees, have become cultural icons, influencing countless other films and media.
