for a film about a killer this be surprisingly dull . nothing much happens and even when thing do happen they do not generate any real excitement or interest . the acting be good from the two lead and cassetti in particular delivers a great performance combine the certainty and stupidity of succo but the rest of the cast also do what they need to . the problem be that there be poor write and direction and the fact that a a true story it isn not interesting and succo be not a unique character and he isn not interesting or exciting . film of this sort normally try to generate tension or empathy or outrage and this generate nothing except a feeling of regret that you waste your time watch it .
