Film genres are categories that define the style, theme, and narrative structure of movies. They help audiences understand what to expect from a film, whether it's a comedy, drama, or horror. Each genre has its own conventions and tropes that filmmakers often use to convey specific emotions or messages. Genres can also blend together, creating sub-genres like romantic comedy or science fiction horror. This blending allows for greater creativity and variety in storytelling, appealing to diverse audiences. Understanding film genres enhances the viewing experience by providing context and setting expectations for the narrative journey ahead.
