A crime thriller with all the cliches of the genre. A good script, the good and bad guys, tension, weapons, blood, violence, cops and gore. Good twist and turns, cunning and unexpected, the last one is terrific, it challenged my understanding, and this is what I liked. A four chapters size looked appropriate to avoid the unnecesary dragging that makes a good product burdensome for viewers. In my opinion for the last twist deserved eight points.
