From this film, I was pleasantly surprised. He begins as a social drama and one is first quite cleverly misled. Soon you realize, however, that much more behind the story than meets the eye. The story is well constructed, very exciting and keeps you a step by step in line. Man with a fever, want to know how to go on and is out of breath in the face of hopelessness of the situation absolutely. The actors are convincing, the story anyway. A great movie to tenterhooks and shudder, with a good mix of shock effects and gradually unfolding backstory. The pace is just right - no boring moments but no hectic succession of shock scenes.
