Horror is a film genre that seeks to elicit negative emotions in viewers by playing on primal fears. Typical conventions of horror films include settings that are already scary like abandoned buildings, forests, or graveyards. The films normally focus on one main character surrounded by death and feature an antagonist like a ghost, demon, or zombies. Subgenres include action horror with fights, comedy horror that spoofs scary movies, psychological horror that plays with characters' fears, science fiction horror with alien threats, and gothic horror about creatures like werewolves and vampires. Famous examples listed are Resident Evil, The Texas Chainsaw Massacre, The Shining, and Paranormal Activity.
