German film based on this real life experiment http://en.wikipedia.org/wiki/Stanford_prison_experiment
It's not too bad. Unsurprisingly it is actually fairly disturbing as you would expect from the subject matter. It's over the top and detached from reality throughout but by the end however it's gets stupidly over the top, turning into something like Die Hard. Which is disappointing because the rest of the film is quite avante-garde and weird. It also has this impossible love story that really gets in the way and stinks up the entire film if you ask me, not that I have anything against impossible love stories but this one really is impossible.
