This movie was great! I am always leary of books-to-movies if I have read the books, but this one was spot on. There were only a few things I could immediately say were left out, and thus far they have not impacted the storyline of the movies.
The only reason I gave it 4 stars instead of 5 was that the way a lot of the scenes were shot made me sick to my stomach and very glad I didn't see it in 3D. If you suffer from motion sickness, be prepared to look away a lot. Some of the actions scenes made me feel ripped off because all I could see was a blur.
