I saw this movie last weekend and I have to say, it was sort of ridiculous. I mean, there was supposedly this dire shortage of water even for drinking never mind washing, but in typical Hollywood fantasy marketing, the female lead had a perfect complexion, without the slightest blemish. Riiiigghhht!
Nevertheless, it is worth seeing for the vision of the coming collapse of ecosystems, and human civilization. A Mad Max scenario, like this one, will most likely prevail (although of course, I hope it won't). Among the outcomes depicted are lawlessness, cannibalism, and rampant sexual attacks. Buckle your seatbelts, etc.
