Film genres are categories of creative works based on stylistic criteria. A genre gives viewers information about a film's subject matter and tone. Common film genres include action, adventure, comedy, drama, fantasy, horror, romance, and science fiction. Romance films revolve around the love story between two main characters and aim to evoke strong emotions in viewers. Successful romance films use techniques like soft, romantic music; warm, diffused lighting; and settings like beaches or schools that facilitate chance encounters between potential lovers.
