I think the last one would have to be The Godfather because it was such a powerful story. There was lots of violence in it but I could take it because I thought there was a reality to it. It wasn't gratuitous, it was just these guys' story.
I love Wagner, but the music I prefer is that of a cat hung up by its tail outside a window and trying to stick to the panes of glass with its claws.
A man who carries a cat by the tail learns something he can learn in no other way.
