"Many things people like, especially if they're young and ambitious, they like largely for the feeling of virtue in liking them. 99% of people reading Ulysses are thinking "I'm reading Ulysses" as they do it. A guilty pleasure is at least a pure one." http://www.paulgraham.com/copy.html
Perhaps a piece of seriously Great Art makes you angry when people ask whether it's Great Art. ;) Instead of things like the themes it portrays or interesting decisions by actors/writers.
