This document discusses genres and how audiences engage with them. It notes that genres provide both repetition through conventions but also novelty through variations, and this combination provides pleasure for audiences. Genres establish expectations for audiences and filmmakers can manipulate expectations for effect. Pleasure comes from both recognition of genre conventions and surprise at an artist stretching those conventions. The document also examines how genres are used by filmmakers, marketers, and audiences to understand a film's format, target demographic, and how to anticipate its structure.
