The beginning to middle is getting to know the characters and their relationships. As the film moves on, the plot thickens and the pace picks up speed. You become more involved, and you question if your theories are correct on what may or may not happen. When the film is done you might spend a while talking to your friends about the meaning of each sin and their relationships to the evil guy.
Enthralling from beginning to end
Intelligent, dark, disturbing and brilliant.
