Genre is an important concept in film studies. Genres are vague categories that films can belong to or cross between based on conventions. The Western genre is closely tied to the origins of cinema itself. Genre creates expectations in audiences and conditions their responses. It allows audiences to understand what type of film they are watching and compare it to other genres. Horror films can be identified by feelings of anticipation, settings, music, camera work and how the plot evolves over time. They appeal to audiences by letting them escape real life fears and anxieties by projecting them onto the characters in the film.
