My attempt to describe this movie without giving anything away:
This movie wasn't bad. I'm always interested in seeing how books translate to film, and overall, this didn't fail. It wasn't completely spectacular, but if you've read the book(s), I'm sure you'll find it interesting and gratifying to see this interpretation.
What I liked:
1. The actors did a pretty good job. I thought they were true to the characters in the book.
2. Effects were well done. I could tell that great care was taken with some of the camera angles, which I appreciated.
3. No major "over-exaggeration." I was afraid this movie was going to be stupid, which would have been easy given the story, which successfully walks a fine line between creative and silly. Thankfully, nothing in the movie crossed into silly, either.
My problems with it were:
1. the storyline felt very rushed - not just the progression of events, but even the dialogue. The actors seemed like they were racing to get words out as quickly as possible, like they were being timed.
2. Wasn't crazy about the changes to the storyline. I feel like this story requires continuity. The climax of this movie was very different than the book version. It wasn't terrible, but it makes me nervous for the possibility of future movies. Did they deviate too far?
3. A little too much action: there wasn't enough down time between action scenes, which is probably why this movie felt rushed. Even action films need to breathe a little. Let the characters develop.
