This drama is pretty good for someone like me who loves criminal dramas. I watched the first 4 episodes while this was airing, but I don't know why I paused it for a while and only continued watching when I got bored. The cases and investigations are well thought of, probably one of the most brilliant cases in Korean Crime kdrama land (unlike Criminal Minds korean version lol) and the actors did well, oh wait... except for Lee Je Hoon. For a criminal profiler who supposedly understands how criminals' minds work, he's too panicky and it bothers me to watch him. In each case, he seems like he's going to have a heart attack. Especially he is acting next to Kim Hye Soo. The ending is somewhat hanging, but hey I heard there's going to be a season 2 anyway. So, I'll be waiting for that!:)
