This is an environmentalist public service announcement masqueraded as a feature animation film. There is barely a story, little twist or climax, and not much laugh.
Is it a shocking revelation that if we keep exploiting nature in pursuit of material gratifications, we'll turn the earth into a garbage dump and ourselves into obese handicaps dependent on machines?

Sorry, you don't get a lot of credit for stating the obvious, no matter how beautifully it is done.
It is such a huge disappointment because the setup -- a trashed earth, a space adventure, and a robot with a soul -- has so much potential, yet none is fully developed into real stories with real conflicts.
