From a physics perspective the technology and physiology of the characters seemed accurate making the movie very cool and a must see. From a political science perspective, the movie demonizes a military funded by an equally evil capitalist corporation seeking energy. The underdogs, "The People" (Communist under tones), who worship their earth are the good guys. They were even called the contemporary term, "tree huggers" a couple of times. I get tired of the Communist/Progressive undertones strategically placed by Hollywood in contemporary media. One of the evil military people transforms in several ways into one of the people after he is essentially re-educated proving that you too can become enlightened and "save the planet".
