From my perspective the Chapman brothers diorama 'Hell' is a technical tour-de-force, in terms of Jeff Koons' work he has the distinction of creating the largest work in porcelain ever with his 'michael and bubbles', another astonishing technical feat. Ironically, you're in the company of many High-brow art critics in your dislike of this work. There's a sense of barbarians at the gates with these kinds of pieces (when they manage to infiltrate the fine art world) that I enjoy beyond their strictly technical appeal... But then I like comics, pop- surrealism (you know, like the stuff you see in Juxtapoz), etc.

You want to really get an aesthetic ulcer you should check out Koons' basket ball and vacuum cleaner pieces! Perhaps a little derivative of R. Mutt, but I think that's the point...well that and a meditation on the beauty of design in mundane objects, commodity fetishism, and a wink at the fine art world in general.
