This drama hooked me right away. It especially gets better at episode 3. Lee Joon Gi in real life has 3 black belts (4th dan in TKD) and the fight scenes are top notch. Just as there are exciting action scenes, there are also some emotional scenes. Wonderful balance between the serious and the light parts. Lee Joon Gi is a one of a kind actor with his natural physical ability and acting skills. Gotta love his spinning kicks and his ability to play a force to be reckon with such as in this drama.
