I'm siding with Mxy. Art, whether it be music, buildings, food, statues, or porn, is entirely a subjective assessment. Art is what you like. It usually has an element of finesse (from which we get the phrase "fine art"), but not necessarily.

As for my choices.... I like Chagall, Matisse, Picasso and (some) Dali (it tends to freak me out a bit though). Looking forward to finally seeing the Disney/Dali collaboration, called Destino.

I really like Rodin sculpture, too.
