I watched this movie last night & I found that some people are trying to figure out something one serial killer...I would give 2/10 rating if this movie would not be true based story..Director tried but direction failed to due perplexed story...It is movie try and error type..someone can understand what is try and error method..I have seen many US movie but this movie was saying system failure of some police system.. what is movie was trying to say to audience it is also not clear...no any type layer in this movie...I think someone was trying to prove how much Police tried to find out a guilty but why He was among them..this movie is not fully professional movie and entertaining movie....director should more concentrate towards enjoyment of audience compare to justify something...
