I thought they did a good job of portraying the book. Of course there were some things that were different, but overall I think it was definately a good movie that was worth my money. I also liked how they made sure they had some of the humor that is found in the book, b/c I think it helps bring the characters more to life for the audience.
The movie was pretty good. There was plenty of action to keep you going. I liked the flashback they had going at certain points too. Overall it's a moive worth seeing.
