So much badassery in this show it was amazing. First: Jang Hyuk and the way he played Dae Gil. I love that the lead character was constantly straddling the line between sanity and insanity; redemption and damnation; coldness and having feelings that ran so deep he must try in any way he could to kill them. Well Played Jang Hyuk! Second: The storyline was interesting and detailed. Along with the mix of drama and humor it kept me hooked to the very end. The cinematography, the pacing; the fact they were constantly on the move kept me moving right along with them. Third: The fight scenes were very cool. Usually I do not like a long drawn out fight scene but I found myself thinking a lot of other dramas could take a lesson from the director and the fight choreographers of this show. Well Done! Watch this if you are hesitating!
