I enjoyed this movie. It isn't lengthy but I didn't feel it was lacking. I thought the characters were developed enough. The animation was very fluid and the shading was done very well to project the right mood. The story line was solid and the characterizations were brought out well by the voice over talents. I think this movie is rated appropriately and parents should consider this. In my theatre there were several young children (under 5 years old) that were very scared.
