As a fan of the books, I was deeply satisfied with this movie. This was my favorite book of the series, and the movie did not leave me wanting.
The movie as a stand-alone though was probably just another average movie. The acting did improve and the special effects were great. But the storyline moved along a little too fast. At some points it seemed a little choppy and they left thing hanging. I'm not even sure a person who had not read the books would understand what had just happened.
Also, it seemed that the there were still some of those over the top, seriously cheesy moments in this movie too. Not quite as many as Twilight, but they were still there. Overall, a great adaptation of the book, but an average overall movie.
