I just went to see it for the second time today and I loved it! This is the best movie of all three, and it was very different from the others. I'm a huge fan of the books and I've read all 5 more times than I can count, I know I'm totally obsessed but I can't help it. I thought this movie stayed very loyal to the books without being so choppy like the other movies. Yes their are some minor differences from the book and it was overall condenced but those things were very necessary, the only way to get the whole thing on film would be to do a mini series. The new Dumbledore I can take or leave, in truth his role was much reduced with Sirius and Lupin having the conversations with Harry that was actually Dumbledore in the book- I'm fine with that. I liked Sirius very much. I had to get used to Lupin (who is one of my very favorite characters in the books) because he didn't look as I imagined him, but that was a small thing and I liked him even better the second time around. Poor Professor Lupin, such a gentle soul. I'm so glad that we were able to see more of Professor Snape this time, I adore Alan Rickman, and I was glad to see that he had a little scene of bravery. Poor Snape is such an unlikable, nasty man that I have to say I've always felt a little sorry for him.
Now on to Harry, Ron, and Hermione. These kids have improved immensely in acting ability! So far I see no signs that they are getting too old, though some of the others changed drastically from CoS to PoA but since that only happens once (thank god!) we won't have to worry about them not being in the next one. It was a bit of a shock to see Neville so tall and thin, and to see the Weasley twins looking like football players and sounding completely different, Sheesh! young boys change so much. I thought the Ron/Hermione tension progressed very nicely in this movie. Shhhh, I'm a closet shipper.
I really liked this movie. Now if we can only have the sixth book!!!!!!!
