I just saw it today! I thought it was probably the best of the films so far, it really benefited from the extra time.
Things I liked:
- The dancing scene; at first I groaned because I thought they were going to push H/Hr again, but it was actually a very good friendship scene.
- R/Hr being given some screentime for once.
- Neville on the train - "Hey losers! He's not here." 😀
- Some great acting - even the usually uneven Emma Watson pulled out the stops for this. Alan Rickman was excellent in that one small scene, you could really see the anger and regret in his eyes when Charity is pleading with him.
- Ron destroying the locket - thank god his character wasn't completely butchered like usual.
- The animated story of the 3 brothers, that was a nice touch.
Things I didn't like:
- Peter Pettigrew didn't strangle himself! That was a great scene in the book, and it was foreshadowed all the way back in the 3rd book! Now that entire speech on the benefits of mercy means nothing, because Harry has never paid back for his show of it in POA.
- "Here lies Dobby, a free elf" - Dobby's rescue and death was well done, but Harry writing that on the tombstone was the most emotional part of that chapter in the book, if not of the whole book. I wish they'd put it in.
- The trio didn't see Luna's room with her "Friends" painting. That was a powerful scene in the book, it really showed the sadness of Luna's character. I was really disappointed with its absence.
- Dudley not telling Harry that he didn't hate him. Again, a good character scene that was cut out.
- No Harry giving Kreacher the locket, and Kreacher becoming more personable because of it.
- No clippings from Rita Skeeter - Harry's anger at Dumbledore and mystery of his past was almost an afterthought.
- "Hi, I'm Bill, I'm the oldest Weasley brother, I'm marrying Fleur and I got attacked by a werewolf last year." - such a blatant infodump, trying to recover after their vicious cutting of the previous films.
- Harry not being in polyjuice at the wedding, and therefore Luna not recognising him by his expression (yeah, H/L fan here).
So yeah, it was a good film, but I was a little disappointed at the absence of some character moments.
