I put this one off because just didn't seem to be my normal cup of tea but after the first episode I was hooked. Lee Joon-Gi sells this one and you can't help cheering him on once you understand his past. A well written story that could have been a shoot-um-up cold adventure but instead it has some heart as the main lead is not a bad ass fighter but I guy trying to survive for his daughter. I like how the reference to old US Films that he copies. This one was seriously underrated. After a little research, I think this one was over looked in the ratings because it was just up again some tough to beat competition when it aired. (The other channel just finished 'I Hear Your Voice' & its direct competition was 'Master's Sun') This is one to not miss.
