The only expectations I had going into watching this show was Jang Na Ra. After watching her in Fated and Old good bye, I had high hopes in her role choosing capabilities. I was looking forward to a positive female lead who plays a cop and can hold her own in a male dominated profession. What I sadly got was a bumbling idiot who rode the male lead's tail coats to solving crimes, couldn't defend herself even if her and at times other people's lives depended on it and couldn't even avenge her father's death despite the fact that this was the reason she became a cop in the first place. I was surprised with the meaty role that Seo in Guk had bagged in this show though. I had only seem him earlier in Reply and his second male lead role in Master's Sun. The role he played in this show was no different from the one I found he played in Reply. He just traded his hat as a lawyer and became a profiler/ criminal studies professor of some sort. What I found enjoyable was that all the major players (excluding of course the female lead) were exceptionally clever people and when the three shared the screen, it was an intricate dance of intellects. Plot wise I lost interest a little later than I do for most series and once the criminals were apprehended, the show simply moved on to the next serial murderer without tying in the loose ends that the previous case had left. Had it not been for my rule of watching things through to the end no matter how bad the show is, I would have dropped it ages ago. This show is a good watch if you have nothing better to do on a rainy day.
