So I just finished the book, and I thought it was really well done with the exception of the (SPOILER)final battle with Harry x Voldemort. Two spells and it's over? Huh. The whole battle at Hogwarts was awesome though.
I don't really understand the purpose of the Hallows throughout the entire thing, though. (SPOILER)They didn't really end up doing much of anything, did they? Or at least, I didn't really understand the significance - they ended up just going after the horcruxes anyway.
Also, (SPOILER)SO MANY DEATHS. But I found myself not caring about any of them except Hedwig's. Well, and Snape, but I predicted his death after I read the sixth book. The Prince's Tale is the best chapter in the history of the series, too.
edit: Oh yeah -
(SPOILER)
I thought the burning and multiplying curses were amazing, creepy, and very original. I liked the idea completely. .that scene inside the Lestrange's Gringott's vault lost me completely. All I recall is them getting burned and me getting irritated at Rowling; it was a lousy bit.
