1) The hide thing is dumb. I have to post this just to read.
2) I'll post more when I know more.
Ok, I agree with most people, but here's one thing that bugged me that no one has mentioned yet.
Poor Snape! All this debate over whether he's good or evil, and what does he get? Nothing. That whole "flashback to let you know he was good" thing sucked. I expected him to turn on Voldemort at the very end, to enable Harry to win, or something like that. But all he got was an ignomius death, making him entirely inconsequential at the end. Sad, sad, sad!
Speaking of inconsequential, the entire Deathly Hallows subplot could have been removed. Seriously, this woman needs to get a new editor (or more likely, just listen to the one she's got). If it doesn't affect the plot, leave it out!
The thing with the ghosts was pretty touching, I'll admit. It was the only thing in the book that really pulled at my heartstrings.
The "19 years later" did feel very tacked on, but I'm glad it was there. Anything that let me know Harry and Ginny were happy together, and Ron and Hermione as well, was fine with me. That's all the "happily ever after" I needed.
I'm still not sure I get the convoluted explanation about the wand at the end. Voldemort was holding the unbeatable Elder Wand (that Dumbledore beat someone to win... how is this wand unbeatable again?), and the Elder Wand really belonged to Harry because Snape killed Dumbledore but Draco picked up the Elder Wand and Harry disarmed Draco who had his own wand and not the Elder Wand at the time, so when Voldemort cast a killing curse at Harry it bounced back and hit Voldemort? Did I get that right? Because if so, I would like to walk up to Ms. Rowling and kick her in the shins. Can ANYONE explain how that makes sense?
Oh, one more thing. I really did like how she got around Harry's death. If anything in the whole series made sense, it was that. Voldemort couldn't die because he'd spread his soul around to various objects, and had accidentally put one of those pieces in Harry. Thus Harry could use the very same power that Voldemort used to cheat death. I thought it was brilliantly done.
