cinema is too vague of a term. there are two types of cinema, movies and films. movies are usually studio features meant to entertain the masses such as The Dark Knight, Spiderman, and so on. Films are usually much more complex and independent a.k.a "indies."
Movies are for entertainment and films are an art form. if you are looking for some culture, hit up some film festivals such as Tribeca and Sundance. they have some great films never released in theaters nationwide because they contain more than just explosions and mindless violence. (although, there's nothing wrong with a good action movie either)
