Although most people would say that Wall-E is the furthest thing from a dystopia you can get but I strongly disagree.
The Best
Rubbish Planet - A plant abandoned because it is covered with litter is a nice concept an interesting version of the apocolypse. THe shots of the rubbish sky scrapers is awesome.
The devolved humans - The ludicrasly fat humans that do nothing but eat and look at tiny computer screens is a pretty accurate look at the western world and I can realy se this kind of thing becoming truer as time goes by.
THe Evil Computer - Another computer knowing best decided that it should kill a few people off to save everyone from themselves.
The good
Return to earth and starting again
Angry robots
THe Bad
Childrens film - I do not want to make a childrens film.
