I just have to start by saying I loved this drama. I'm saying it in a very biased way. Why? Because it is EXACTLY the type drama I like. It's as if it was custom made just for me. This is a drama only OCN can succeed in making. Overall the same style as TEN. A special team is formed to help in the recovery of missing individuals. If I were to compare it to TEN, I'd say I liked the way the the team was formed there more than here, where we got to know the characters before the team was formed while in M, it felt a bit rushed. Otherwise the idea is similar. The focus is on the human side of the perpetrator and the victim. Many times it's hard to identify who is the real victim, and it's hard to hate anybody. On a more subtle note, we got into the politics of law, and the meaning of justice. The lead characters were amazing in their roles, and so were the guest appearances in each case. Kim Kang Woo as Gil Su Hyun was such a troubled character. He has a deep darkness, and an extremely cute side. I love that he's no cheesy idealist. He will get blood on his hand, not for the sake of justice, but only to make the world a bit less awful. He's not faultless, as we see his view is not absolute, but he seeks the same satisfying ending I want. His frustration would always reflect mine. Next is Park Hee Soon playing Detective Oh Dae Yeong, who's personality it pretty much the opposite of Su Hyun. He's pretty loud and outgoing, and his life is mostly in the light with a happy family. He got many years of experience making him very perceptive. Seeing his trail of thoughts and the way follows track is engrossing. The two guys have the chemistry and the perfect foil for each other. Rounding up the team is Jo Bo Ah as Jin Seo Jun. Though much younger and beautiful, she did convince me of her being a focused hacker and smart. I enjoyed the sunbae-Maknae feel. Other interesting characters were those involved in the cases. Though Su Hyun was supposed to be the genius of the show, those perpetrator were the geniuses. The performances were dazzling for a number of cases totally broke my heart. Other than the cases and character, I like how the theme was forming subtly little by little each episode, until we got to the last episode. I find they quoted it perfectly: - Currently we are living in a world that's filled with the fruit of injustice - A History of injustice manipulating justice to kill off justice I enjoy my mysteries, but since it is embedded so well with such a deep theme about law and justice, it reveals a deeper message that the drama is telling the viewer, leaving us in deep thought about the matter. I would highly recommend this drama for anyone who enjoyed TEN or OCN dramas, and mysteries in general. There isn't any romance but, there is bromance at a more understated level as well as camaraderie.
