We all know that Hollywood films and their counterparts elsewhere obey certain conventions of style and story. (I say conventions to put it neutrally. Some will call them formulas, some will call them clichés.) Against that tradition some critics and film lovers posit what’s been called “festival cinema” or “art cinema,” a tradition that favors individual expression and more unusual storytelling. But can we say that this tradition also has its conventions?
I think so.
An art film may give us nascent conflicts but never develop them, or pay them off. Characters may come and go without preparation, and chance events may divert the plot. Are these tactics more realistic than what we get in tightly plotted films? Some would say so; they’d say it’s more like the way life moves. In any event, it’s an important convention of this filmmaking tradition.
Parallels matter more than causality in many art films.
