Genre cinema refers to films that are categorized based on specific themes, styles, or narrative conventions. Common genres include horror, comedy, drama, science fiction, and action. Each genre has its own set of expectations and tropes that guide storytelling, character development, and visual style, allowing audiences to easily identify and connect with the film. Filmmakers often use genre conventions to create familiar experiences for viewers, while also experimenting within those boundaries. This can lead to sub-genres, such as romantic comedy or psychological thriller, which blend elements from multiple genres to offer unique storytelling perspectives.
