<raises hand> I've poured over all of the books several times, have them all on my mp3, and have my tickets for the movie!
I, too, was not thrilled with everything in the fourth book. I can agree that she doesn't have the seasoning or wit of Rowling, however she does do a great job of getting the emotional pull into her books with characters that you like no matter the literary flaws. The plots aren't complex, the reading level isn't terribly high, but still I found them very enjoyable.
On a larger level, Twilight mania is HUGE! Maybe we'll find a Twilight or Edward pattern here next year.
