Nothing about any mad max movie was realistic. A group of kids living in a green canyon out in a desert waste land? Come on. A hand full of gay bikers marauding the post apocalyptic world in which a single civilized colony of innocents salvaged an oil refinery, and they managed to escape with one bus load of fuel? Mad max is about glamorizing a societal break down and a mad hero who manages to rescue all but himself. It's not a depiction of any real possibility.

I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago. Edgar Allan Poe
