I think all of their close escapes are well played out. It wasn't even how quickly they found everything (that was disappointing, but they did have a lot of help, even if they didnt know who it was). It was the epilogue that killed me. It had no information. Yes tell us who married who and all that, but ten years of books and thats how it ends! What happened to everyone else. that chapter would have been fine if after it we would have learned what careers they went into and what about george? And Luna and Neville?
But i still LOVE all the books, 7th included. one bad chapter is forgivable if you ask me.
