If you're looking for an action-filled drama of hide-and-seek with a murderer, then this is not the drama for you. But if you're looking for a thought provoking drama where you can spend half the time guessing whom the murderer is, and the rest of the time studying the abilities of the human mind; then this is the one for you. This drama is based on the question "Are monsters born or made?" and focuses on the psychologic part the story. Now before you back away (I know I usually back farfar away from movies that have a psychologic theme) this one is really worth the watch! There were frustrating parts and questions that weren't fully answered. I also wish that there had been more shown about each characters background. I rated the rewatch value low only because of the fact that once you have watched it, you will already know how it will end and who the murderer is. Over all, a very interesting and thought provoking story that pulls you in and allows you to ponder about one of life's greatest questions; "Are monsters born or made?"
