I thought this movie was absolutely excellent in every respect. I thought the movie itself was constructed beautifully. For anyone who has thought that the Harry Potter franchise was just "kids' stuff", this should totally dispel that theory.
I found the camera shots and the scene edits to be handled very impressively. I particularly loved the "story within a story" when Hermione tells the tale of the Deathly Hallows. I felt that I wasn't taken out of the immediate action, so much as immersed further within the tale.
I also felt that the acting in this film, as a whole, was supremely improved over the other films. Every word, every look was spot on and natural, totally true to each and every character. I particularly thought the 3 primary actors have finally shown that they ARE talented actors in their own right. They didn't just play these characters, they BECAME them. Previously I've found Daniel Radcliffe to be a bit stiled with his acting, but in this film I felt like he showed himself to be a superb actor, worthy of playing this cherished role.
The film completely carried off the tone in the final book as well. This is clearly darker than the early Hogwarts years, and the movie has been very true to that. Every scene in this movie(as, I felt, in the final book) is important and exciting. I felt excited and involved through the entire movie.
I feel this is by far the best of all of the Harry Potter movies in every respect and I can't wait to see it again!
