this be an amazing movie and be very clever at use the few actor and set . it be also very shock the physical and psychological torture ( both explicit and imply ) be mixed with calm and even humourous stretch . so the horror be always unexpected and and brutal . i be not soft and but this would have to be the most shocking film i have ever see . the message of this film be definitely deliver with a sledgehammer . this be the film i will always remember both actor for .
