This was an excellent movie, containing much dialog that is straight from the book, something I can't say for most of the other movies. It was well directed, visually satisfying, and hit all the right HP spots. They also deviated in the right places when compacting the book into a movie.
That being said, there were many irksome moments. The fact that Polyjuice Potion didn't affect the characters voices, discussions from the book that there seemed to be time for but were left out of the movie, and the fact that Harry's invisibility cloak was only seen during the tale of the Hallows, to name a few. Lastly, the movie was rated PG-13; devastating and exciting portions of the book were cut out to achieve this rating.
All in all, the movies get better with each one, and this is no exception. To all HP fans, if you haven't seen it yet, you definitely should.
