Saw... then The Cube and many other films which I have saw or I will be on the way to see are brutal. But as far as last which as for now I have watched is Old 37, it's very brutal.Unfortunately, I will call this film or I will add that there are facts out there which show that it's based on true stuff. There are outside such type of people which do such thing, that you haven't saw. Feel happy, if you see them you won't go back you should run.
