Reading the blurb about this short tells you nothing really about what happens. Then watching it doesn't really give you much more to work on. Some decent filming, but ultimately lacking any purpose, meaning, significance - and crucially, interest. Short, but not worth the effort.
Interesting if you're willing to go through everything after watching the film, because nothing's even giving a hint to what this film is really about. It's all about the assembly. But yeah, the "twist" is a bit unrealistic since so close to the population. All in all, not that interesting afterall in my opinion. I preferred the short Trafic, which won the Palme D'or in 2008 if I'm correct.
