A horror franchise is a series of related films, books, or other media that focus on themes of fear, suspense, and the supernatural. These franchises often feature recurring characters, settings, or storylines that build upon each other, creating a larger narrative universe. Popular examples include Halloween, Friday the 13th, and The Conjuring series. Horror franchises can vary in tone and style, ranging from slasher films to psychological thrillers. They often attract dedicated fan bases and can lead to merchandise, spin-offs, and adaptations in other formats, such as video games or television series, further expanding their reach and influence in popular culture.
