Does not capture the essence of the book. If you have read the book then you will understand the disappointment felt when a movie just fails to live up to the book (Harry Potter 5 anyone? xD). It really is just sad to see a well loved book be lost in the transition from ink to film.
The movie itself is ok if you havn't read the book, it has nice special effects, a ok told story and cool characters but what is lacks compared to the book is a brilliantly told story (which is executed badly in this movie), fantastic character's with amazing backstories, and just the essence itself. The story feels rushed in this movie, very rushed and disjointed compared to the book. If they even added just twenty minutes more to the movie it may have been slightly better.
Some character's were changed which didn't suit ‘normal human’ motives. Like that priest guy who's all Wormtongue like and your just like, oh great another cliche bad guy.
Just found this film rather disappointing, sorry. =(
