the ONLY thing wrong with this film...
is that they would have been covered in blood after each murder.
otherwise, i give it a 7.9/10 and the only thing that brings it down in my mind immediately is that it occasionally reeks of improvised dialog but then again, the parts that seem "wrong" are when the dominant one repeats questions or main expressions but that indicates something deeply wrong with him and his reasoning/perception of reality.
i think it's a brilliant film. prove me wrong.
