I know that this movie flopped in the theater, but perhaps it is more a movie to set your kids in front of. The animation is well done, and the moral of 'make the best use of your attributes, and don't try to be what you're not' is great. There isn't a lot of real depth, and the villain is rather James Bond-ish, but the voices are wonderful.
Enjoy this film... just for the fun of it! I might mention: A lot of animated features are as much for an adult audience as a juvenile one. I don't think that was the intention, here. Even so, I enjoyed it immensely. I just had to not expect something aimed at my age level.
All in all, just a cute film!
