Query: good, but not great

I've heard such good things about this book and was disappointed once I got around to reading it. It was good, but not great. I get the sense that this is one of those over-hyped, over-rated books that come down the pipe every year by the latest "new, young writer." I'll look forward to reading what Diaz writes in the years ahead. For my taste, he hasn't hit the mark yet -- but maybe in the future he will. Worth a look, but no big deal.
