As a fan of post-apocalyptic movies, I must say that this movie is as far from post-apocalyptic as a post-apocalyptic movie can get. The majority of the movie is explained on the back cover- Mad Max is a cop whose family has been killed and he must seek revenge. But the seeking revenge part is just about 4 or 5 scenes towards the end of the movie! And to top it all off it seems like the apocalypse has had absolutely no effect on the world, because trees are growing, there's power, water, civilization, medicine, and ice cream! Jeez!
