This movie doesn’t follow the most basic rules of story telling. It is important you understand this, the movie delivered a problem, a guy kills people his wife sleeps with, that is all. You have no idea how they met, who he is, who she is, why they are in a relationship or even what the point of the story is. There is no climax, there is no resolution, there is no twist. This screenplay was written by a 12 year old in an hour.
