There is plenty of drama and action and many great characters. The characters are made memorable by a set of brilliant actors. The story is good, though at times, (like after several major characters pass away) it seemed as if there isn't much for the plot to go on. Then new problems were created and the story goes along. The transformation of Baek Dong Soo from a deformed kid to the stunning warrior is a long journey, and is shown through the course of the drama with realism and beauty. The character of Yeo Woon, who is the other pillar of the drama, is equally strong and leaves an impression. Among the characters, The Sky Lord and Sword Saint are very impressive. The female characters are very resourceful, and not clingy or weak. The negative characters are highly selfish and evil. The main villain is very annoying with his typical "Villain"ish laugh. The music is pretty good. I especially liked the music in the climax fight scene inside the palace. The series does drag at times, when it focuses too long on melodramatic scenes, but it's an entertaining watch except for the way they choose to end it. My only suggestion would be to wind up with the second last episode for a good ending, because the last one leaves us disillusioned.
