A decent crime / mystery with solid acting. The pros of this drama: I watched the plot unfold with enjoyment. The pacing is good so it keeps viewer engaged. The acting is good - especially the little girl and Ji Sung as the Jeong Woo. The reason I do not rate it higher is that I found it really derivative of other shows. Though I did enjoy it, it was pretty predictable. I usually don't care about this so much, but here it was so obvious that it distracted me from getting emotionally involved with the characters. I didn't find the characters very realistic or complex. The characters felt so much like stock characters from very other crime mystery story of this type. It's like the writers decided they wanted to write a show like "Prison Break" combined with "The Fugitive" and just went with that without trying to add any originality or twist of their own. At first I thought the references to Prison Break were kind of cute, but after awhile the similarities became tiresome. I didn't love the characters - not even Jeong Woo. There were details about him that bugged me, so though I wanted the bad guy to be punished, it's not because I loved the hero so much. The setup for the villain really didn't make sense. The crime that is the catalyst for the whole drama was psychopathic and impulsive and really without thought or reason. He gained nothing from it and just did it because he felt like it. Then he spends the rest of the episode impulsively covering it up. And then we are supposed to believe that he magically transforms into a resourceful, manipulative character who plans and thinks enough to get away with all that he does for the next 17 episodes? The motley group of inmates was kind of funny, but too glaringly cute for this type of story and obviously just there for comic relief. I don't regret watching this, but didn't love it. It's one of those shows where I just wanted to see the story play out even though it was mildly disappointing along the way.
