Did you check out the pretty darn entertaining Guardian interview with Maurice Sendak? There's some strong hateration in there, for everything from e-books ("I hate them. It's like making believe there's another kind of sex. There isn't another kind of sex. There isn't another kind of book! A book is a book is a book") to Gwyneth Paltrow ("I can't stand her.").
Between all the the money quotes, there's some interesting background on Sendak's life. Who knew he was such a saucy character?
