Amazing! It is as good, if not better than City Hunter, which was so far my favorite action drama, and this one trumps it. Drama has it all: Fast-paced action, forbidden romance, murder mystery surrounding childhood friends, missed connections and reconnected family, political thriller, etc. Ji Chang Wook managed to make the action scenes look really bad ass and cool and so hot and sexy at the same time. His performance as Healer and alter-ego dorky nerd Park Bong Soo are equally endearing. Park Min Young also slays as the inquisitive reporter and their chemistry on-screen is sizzling. The rest of the cast, especially Kim Mi Kyung, round up the drama with solid acting skills. Healer sets the bar when it comes to Korean Action drama, will be hard to beat.
