Loved that movie -- the most light-hearted and delightfully tongue-in-cheek of all his movies, IMHO.
I can appreciate why any of his movies are disturbing, though. He has a talent to beautify violence, make it highly aesthetic & stylized. Whether one sees it as a comic-book treatment or deeply disturbing is a matter of perspective. He is definitely a talented artist, though. In my book.
I hate the movie "Confessions of a Shopaholic" for a lot of reasons, but the biggest is how they make light of and cheapen a very serious problem, and the book didn't really deal with it so much as throw weiner at it as a magic cure-all.
