This is a really FUN KIDS' MOVIE! it is excellent for what it is (a kids' movie). Lots of laughs for both the kids and adults, and my 8 year old wants to go see it again. We went with a group of 10 kids (boys and girls ranging in age from 4-12) and 4 adults and everyone in the group had a lot of laughs, and a good time. totally worth it.
i don't usually care for kids movies, this is definitely one of the better ones. it follows the book pretty closely, so if you kids love the book series, they will love the movie. have fun!
