Importance of genre

Much of the pleasure of popular cinema lies in the process of the "difference in repetition"- I.e. recognition of familiar elements and in the way these elements might be orchestrated in an  unfamiliar fashion or in the way that unfamiliar elements might be introduced. - Steve Neale (1980)

Genre is constituted by "specific systems of expectations and hypothesis which spectators bring with them to the cinema and which interact with the films themselves during the course of the viewing process." -Steve Neale
