The Sigh of Haruhi Suzumiya

I recently read The Sigh of Haruhi Suzumiya, the second book in the series of Haruhi Suzumiya novels (at least in the U.S.). I've seen some negative reactions to it, but I'm not sure why. Haruhi's absurdity and Kyon's acid responses are still funny. There are also hints of a larger plot running through the novels as a whole.
