It is brutal, relentless, nihilistic, violent, terrifying, relentless, psychopathic, and yet it is so powerful, so explosively febrile, it compels you to watch and keep watching.

Two problems I had with the film were that the subtitles were too small making them difficult to read and that they did not remain on the screen long enough to adequately read. Nevertheless, it is an amazing movie and well worth your time.

It doggedly refuses easy ways out, and it has the guts, brains and critical eye to plumb the roots of terror and its bloody consequences.

Director Uli Edel and producer and screenwriter Bernd Eichinger don't take sides. They don't condemn, but nor do they excuse. Instead, they leave us to make up our own minds.
