The animation in this movie is beyond anything I have ever seen or imagined. It is so good that you almost forget it is animation. The story line is a little bit mature for children and sometimes the movie is so caught up in the backstory (i.e. first 15 minutes and last 20 minutes) that our little ones lost interest. However, it is definitely a classic. As an adult, I loved this movie. Our 5 year old noted that Monsters v. Aliens was better. And that is the why only 4 stars. This movie is much more for grown ups than for little kids. Oh, well. Still a great picture and one worth seeing and adding to the DVD collection
