Battle for Terra
A simple, but novel story that presents a peaceful alien race that is threatened to extinction by an invading army of human beings.
The engaging aspect of this movie brilliantly portrays war in one of its true forms: the tragic struggle between two powers for a critical element of their existence with neither being the clear "right" or "wrong" side.
Even though the "happy ending" of this movie is expected from the very first scene, it still comes as a long-desired surprise.
This movie was very well-done. It is not really much of a "kid's movie;" consequently, the golden elements presented in this film will probably be completely missed by children and the battle scenes at the end will not really be the exciting "Monsters Vs. Aliens" climax.
