I just finished it tonight. I thought it was OK, nothing too mind-blowing, but then again, I hadn't been hanging out for this book, so it was good enough for me.

(SPOILER)I liked how each of the Horcruxes was destroyed by a different person.
Diary - Harry
Ring - Dumbledore
Locket - Ron
Cup - Hermione
Diadem - Crabbe
Harry - Voldemort
Nagini - Neville

I always thought the sword would pop up again, and I'd hoped that either Ron or Neville would use it.

The whole "come back to life" thing was a bit too similar to Jesus and The Matrix, I think that if Harry was going to die, he should have stayed dead, and somebody like Neville, Snape or even Malfoy (any one of them) finish Voldemort off.

After I read Lupin and Tonks dying suddenly in quick sucession I was a bit annoyed. I liked both of them and I think Tonks definitely should not have died. Aberforth was a much better candidate for the role of sacrificial lamb. And as for Hagrid, that oaf should've died TWICE, but was kept alive just so he could get a mention in the sunshine-lollipops-and-rainbows ending. Apart from the last two lines, I thought that epilogue was a huge disappointment. Hell, I would've been happier if it had ended before the epilogue, despite the fact it would then lack closure.

I still have a few questions, though.

(SPOILER)Why did Dumbledore give Hermione the book in his will? The other items' importance was clear (The Deluminator helped Ron find Harry and Hermione again, the snitch had the Resurrection Stone in it, the sword ended up destroying three Horcruxes), but the book had no discernible purpose, other than to make Harry go within an inch of screwing up the mission entirely (he almost talked to Ollivander first at Shell Cottage)

How could Dumbledore have defeated Grindelwald? The Elder Wand would mean Grindelwald could never lose a duel, and the book clearly states, several times, Dumbledore duelled him and won, then took his wand. I doubt Grindelwald would have chosen to use a different wand, or gone easy on his former friend.

Why did Dobby have to die??

One more thing. Has anybody counted how many time the word 'beam' and variations was used?
