"I'm suggesting that the actual experience of enjoying or not enjoying a piece of art has relatively little to do with its attention to form"

Maybe for The Hangover 2, but not for, y'know, art. Of whatever type. For example, when I watch or listen to the comedian Richard Herring, I've often literally laughed so hard I become out of breath, can't see, turn red and get a buzzing sound in my ears. But that's because Herring (at his best) plays with the form of stand-up comedy, doing things like telling an extremely dull story and then repeatedly extending it, threatening the audience that it will continue til they all laugh.

Or listening to The Warmth Of The Sun by the Beach Boys, I can tell exactly why I love the song, and it's because of the key change on the third bar, and the way that breaks a standard pattern and turns it into something magical.

If all you're getting out of art is what you're bringing to it, you're probably not looking at the right works...
