I thought that this movie had a different mood than the latest movies (specifically "Prisoner of Azkaban", "Goblet of Fire", and "Order of the Phoenix"). There was more of a comedic and lighthearted element that really made the movie enjoyable to watch. The movie also did a great job at following the book. There are only a few scenes that did not come from the book and they were great additional touches. Even as a big Harry Potter fan I thought that they were not betraying the book. Overall, I believe that this movie was a great representation of the book that J.K. Rowling produced and if the improvement continues than the next movies (the two parts of "Deathly Hallows") will be the best of the entire series.
