Ditto to Walrus's.
I don't like Dali just because I'm sick of his stuff. That is my best explanation, first time I saw it I was impressed. Now, I just am sick of it. In contrast, I see Van Gogh just as much and I don't get sick of his stuff, ditto with escher.
I want to point out that i HATE Warhol, his paintings and especially his films.
