In these 12 episodes I think the first two cases are quite good and the details are also quite good And easy to understand but the essence of this drama is about Profiler and most of the Profiler is to identify serial murders but serial murder cases in this drama actually look very absurd serial killers don't caught by the police after being identified, but caught due to negligence during the act of murder, this serial murder case is what makes this drama destroyed even though the core of this drama is about serial murder I think in these twelve episodes I can see alot of unique cases but delayed due to serial murder cases, especially the very few episodes, making the rating not going to be high.

And what makes me feel very absurd is that serial killers who only have photos of their backs,they make a list of wanted people, but serial killers who they have the drawing picture of the culprit's face they don't put them on the people's wanted list so that it makes alot of other victims fall ,, in my opinion very not makes sense
