That sums up my review: perfect. This movie was phenomenal. They filled in the blanks perfectly, and the visuals in this movie were mind-blowing. I saw it in IMAX 3D, and it just blew my mind-hole. The soundtrack was amazing, the visuals were stunning, everything about it was great. I couldn't say a bad thing about this movie.
Take into account that I haven't read the books. In comparison to some of the other movies, this was not the best of the series. Though it did deepen the story line quite a bit, there were plenty of parts that seemed to drag a bit, with a lot of suspense and emotion. I was expecting a little more action from the movie then I received; however, the movie standing by itself was still excellent, and certainly established a hefty wait for Part 2. I saw it at midnight, waited for hours, and certainly do not feel disappointed in any way. I just felt that Goblet of Fire and Order of the Phoenix were a little better.
