I'll go through my judging panel wise. 1) Story? Oh, its genius. I have never liked supernatural and time travel on real life characters except "Back To The Future Series". But this story line is mind blowing. The depiction of a gone era and its generation in relevance to the present era and its respective generation. The perspective of how it is now and how it was back then. The warrior-doctor love story was sewed amazingly. The action kept me in their grip. This is another one beside "King2Hearts". Whoever liked "King2Hearts" would surely like this! 2) Acting/Cast? Oh, again a marvelous casting team made the story embrace you by coming alive. How Lee Min Ho is concerned for Kim Hee Sun. And watch out for the acting. It was what made this drama. 3) Music? My favorite is the Princess Nogoong's track by Ali. And also the main song! The score's wonderful. Overall, Good work. Although directions and enhancement of a scene at some points could have been much better but somehow at the end of the show you feel that it has been compensated anyhow! I liked it. Now, do you really wanna ask me about the rewatch value? :P I don't think so. Go and watch it!
