Audience Expectations - Comedy

Comedy Films are "make 'em laugh" films designed to elicit laughter from the audience. Comedies are light-hearted dramas, crafted to amuse, entertain, and provoke enjoyment. The comedy genre humorously exaggerates the situation, the language, action, and characters. Comedies observe the deficiencies, foibles, and frustrations of life, providing merriment and a momentary escape from day-to-day life. They usually have happy endings, although the humor may have a serious or pessimistic side. 

Comedies usually come in two general formats: comedian-led (with well-timed gags, jokes, or sketches) and situation-comedies that are told within a narrative. Both comedy elements may appear together and/or overlap. Comedy hybrids commonly exist with other major genres, such as musical-comedy, horror-comedy, and comedy-thriller. Comedies have also been classified in various subgenres, such as romantic comedy, crime/caper comedy, sports comedy, teen or coming-of-age comedy, social-class comedy, military comedy, fish-out-of-water comedy, and gross-out comedy.

Comedy is a genre of film that uses humor as a driving force. The aim of a comedy film is to illicit laughter from the audience through entertaining stories and characters. Although the comedy film may take on some serious material, most have a happy ending. Comedy film has the tendency to become a hybrid sub-genre because humor can be incorporated into many other genres. Comedies are more likely than other films to fall back on the success and popularity of an individual star.
