DH and I saw it and lunch and enjoyed it. It wasn't totally true to the book, but since movies rarely are, it was all good. I was just amazed at the number of little kids in the theater (under 4). We saw one lady who had four little ones with her who had to leave 1/3 of the way into the show. The kids were well behaved, but all of the battle scenes were scaring them and a good amount of the movie seemed to be fight scenes so....
We'll definitely be getting it on DVD, and I'm really hoping they'll decide to continue with the series.
