I can't stand films that oversimplify problems and offer juvenile ways of solving them. That approach does not help at all.
Here's the theme of this laughably myopic flick: Pollution is bad! Solution: get rid of all the pollution!!!!
Seriously, that's as deep as this gets. If you're an idiot who doesn't already realize that "pollution is bad!" then sure, go ahead and watch this film. But to the rest of us--a world of people who are struggling to find answers to this complex problem of how to reverse the damage we have done whilst continuing to thrive as a society--this film is little more than a child's notion of how to save the world.
It reminds me of the idiots who parade around with catchy picket signs like "make love not war!" and "flower power!" (the latter of which is *literally* the theme of this movie). Oversimplifications like this do not help.
A few words about the graphics: initially impressive but somewhat shoddy on closer inspection. Someone obviously spent a lot of time rendering these images, but he or she failed to pay attention to the details that would have made it realistic. For example, when the man walks, he seems to be weightless because the animator did not realize that people slump slightly when their feet hit the ground. Overall I guess it's a good first attempt, but the animator should study human movement more carefully before trying again. I've seen Atari videogames that are more impressive.
