This is one of the best animated movies to come along in long time, let alone the best 3D movie I've seen. The 3D experience was very good, maybe not the best effect but the story more than makes up for the better than average 3D overall experience. There were scenes in the movie that the 3D sound and visuals were state of the art. This story starts out a little slow but picks up pace quickly. The characters were all interesting, and actors voices fit the characters very well. One caveat, some smaller children might find the action sequences a bit frightening but my 6 y/o took all in stride.
