Yes, I was hardcore and did the midnight showing of Harry Potter last night and it was awesome and totally worth the lack of sleep! (Especially since I took a half-day and didn't go to work until after lunch so not too bad.)
I really think all the HP movies do a fabulous job of translating the books into movies, adding and deleting scenes so we get an excellent visual of the 700+ pages of text in 150 minutes. Especially since I haven't read this one (or any of them) since the Deathly Hallows release, my memory was a little too vague to be picky. My main thoughts on the film, and feel free to discuss in comments:
Beware coming spoilers for this movie/book and the next.
Is it just me or did they foreshadow Snape being on the good side a bit more than the book does? One of the reasons I re-read all the books before the last one came out was I determined to find some sort of clues about where Snape's loyalties lie and came up with nothing. I think the movie gave more pro-Snape clues.
Where was the battle?! The Death Eaters attacked Hogwarts, they didn't just come to watch Dumbledore die and bust some windows.
A little more Ginny and Harry time is always appreciated.
I can't remember how important the Percy vs. rest of the Weasleys tension was in book six, but a lack of Percy in this film makes me concerned he might not be in the next, and one of my favorite scenes is when Percy comes to Hogwarts to fight and they have the big family reconcilation before the final battle.
Emotionally, I held up better than expected. Normally when I read Dumbledore's death I cry to the point of sobbing sounds and moans, but last night I kept it to a steady stream of tears. Although I must admit, I started crying before they even made it the cave. The whole "You have to do exactly as I say even if that means leaving me and saving yourself" speech...*sniff* *sniff*
I very much appreciated the extra humor in this film as it helped soften the ending a bit. I don't think I've ever laughed so much during the movies.
All of this reminds me how much I want a Book 8.
