I would have rated this drama a 10 if not for a few episodes toward the end that I found ridiculous.... Cast: Ryu Tae Oh - he was my favorite character (of course he was evil) but no matter how evil he was I couldn't bring myself to fully hate him b/c he was just too darn good-lookin' ;) and I think their was a shred of a human hiding deep within him.... I liked his scenes along with Ji Wool - their scenes together were always good. Mad Monk - he was a pretty good detective and I liked him for the most part. as for Doc Maria - she was ok and then not ok - I found a lot of her scenes to be ridiculous. I hated one guy in particular (but to say who would probably be a spoiler). Story: based on real events - I'd have to say they did a great job on this drama - I liked every episode except for a couple closer to the end with about that one guy I hated. I like the "lesson" they talked about at the end. Music - Really really good! love the ending theme the most! Re-watch value: possible - but I would be skipping and watching mostly only Ryu Tae Oh scenes lol
