I'm late to the party, we were out of town and did not have internet access. My thoughts.
The Snape storyline was amazing, pure perfection. His end was sudden and brutal, but it worked well. I suppose the thing that made Snape such an interesting character was that he was so conflicted, and it all came out in his relationship with Harry - torturing him in school, but pledging to save his life at the same time. I don't think Snape's dislike for Harry was ever diminished, he just did it all for Lily.
Dumbledore, posthumously, turned out to be a much more ruthless, flawed, manipulative and complicated character than I ever imagined and JKR thoroughly debunked the whole saintly twinkly image he's had for the last six books. Personally I loved this unexpected development, I look forward to re-reading the series with this new twist on the character in my head.
Where was Ginny? I was REALLY disappointed here. She has been set up in the past two books to be a butt-kicking character, but in DH she didn't really DO anything! Ginny's been around from the get-go, she's the girl Harry loves, everyone in the previous books talked about what a powerful witch she was, and she doesn't do much of anything, except snog Harry and get pissed off, once again, that her parents are overprotective and she has to be left behind. Seriously, if there was anything that actually sucked about the book, I'd say Ginny's second-class status was it.
I was also disappointed by Lupin and Tonks deaths. Could not even ONE Marauder have had a happy ending? Geez, was this group given a raw deal or what??? But even worse was the one lousy sentence relating their deaths after the fact--surely Remus Lupin, once a Hogwarts teacher and a friend to Harry and, oh, you know, the LAST REMAINING CONNECTION HARRY HAD TO HIS PARENTS, deserved better than that.
I am sick over Fred's death, even though I had a feeling it was coming (I assumed George would go with him). I'm glad he was at Percy's side. And I don't know that I'll ever get over Dobby's death....such a touching and sad part of the story. And Hedwig. So sad. Although I was a little disappointed she died helpless in a cage, I would have expected a different end for such a noble character.
Ahh, what else. Loved the return of old characters like Lee Jordan and Dean Thomas and Oliver Wood. Loved Luna's house and her paintings. Loved Neville got his moment to shine. I also really liked Dudley's moment of humanity when the Dursleys finally left for good. Didn't see that one coming at all...I knew there was more to Dudley but that was not what I expected.
I liked the epilogue but wanted more details...nice to know everyone ended up happy and married with kids, but what are they all doing for a living? It should have been about 10 pages longer....
All in all, I was very satisfied with the book, but so very sad that its over. Its almost like a death in a way, my whole family feels the same way...we all are sort of in mourning around here.....
Looking forward to reading through this thread and reading everyone's thoughts......
