As they already said that this is the Korean version of American famous TV shows, Criminal Minds, so, the plot and the contents will be the same. The only fact I don't like is that they skipped the cases I like and changed a bit. Casting is good except for the team leader. I feel that he is not the right one. The rest are fine. I like they chose her to play in tech analyst role. She's perfect. Too bad the knief is censored. I wonder why. All in all, for entertainment, it's quite good. It's watchable.
