I've seen it 5 times now. Wow, did I just admit that?
LOVE this movie. Love, love, love. There were some things that bothered me, but on the whole, I was very happy. (Obviously, LOL, since I've now seen it 5 times and plan to see it more times while it's still in the theatre.)
As a Ron fan, I have to say, I was so very, very happy that we FINALLY--after SEVEN MOVIES--saw the real Ron from the books. Rupert Grint has always been good at bringing out flashes of him, but I think the filmmakers always held back from giving him material that he could really sink his teeth into, and as a result, movie Ron always came off as goofy and kind of a lightweight--so different from the Ron in the books. This one, the difference is pretty stark, and it made this Ron fan's heart overflowing indeed. It's not hard to see why Hermione is utterly and madly in love with the boy
