Xavier Gens throws a lot at you in an opening act that does not really reflect what this film is about - eight people trapped in an enclosed space with limited rations slowly going insane. It's an atomic Lord of the Flies, and it's pretty fucking bleak.

At first I thought Gens had blown his wad too soon, the film literally starts with a bang and the response of the characters was not at all convincing. They go from "holy shit that just happened" to "I'm going to bitch and be tedious" within minutes. But then shit gets mental, the film cleverly hints at some far out sci-fi dystopian context only to then hunker down, narrow its focus, regain its composure, and settle itself for a very depressing observation of human deprivation in the face of certain death.

Hats off to Jean-Pierre Taieb for an incredible original score (think John Murphy with a dash of Clint Mansell), which really brings out the emotion when Xavier Gens pulls out a whopper of a finale. This is the best film I've seen in a while, it's probably the best post-apocalyptic/ dystopian film I've ever seen and I sincerely hope it blows up the box-office so that Gens can make another.
