I saw "Saw IV", is an film directed by Darren Lynn Bousman. I chose this film because the first time that I saw this film I liked.
During autopsy of John Kramer, they find wax coated a Microcassette in his stomach. And say that the inspector will be tested in games. The protagonist is a black man named Rigg, friend of two persons tried in games.
I like this film because do not expect the end. It’s cool.
