Story: It has some interesting parts and some parts that make you go "Huh?" The chemistry between the leads were so-so. The romance development was not instantaneous and you only get to feel that they might be in love towards the second half of the drama. The beginning was super annoying with the woman screaming and doing really IQ-defeating actions (come on! she's supposed to be a doctor,, show some intelligence please!). I personally watched the first 4 episodes to get the intro, went into a short break, fast forwarded the middle parts and really seriously started to watch around episode 16 onwards when the story finally started to pick up and gear towards the meat of the drama. The ending was acceptable - at least the writers avoided cliche mind-boggling endings. At least the ending has some logic in it. There are some parts of the drama that were not properly explored or explained and deaths of certain important characters that were not properly accounted for (as if they wanted to rush the deaths so they could get to the ending). The drama could have been so much better if some lose ends were tied up nicely and they work more on the chemistry of the main couple. Acting/Cast: Generally, the acting was good. Even Ice Prince/Stone Face Lee Min Ho acted well in the role of a general (which requires one to be quite expressionless since he's an emotionless killer and all). I would really like to see Ice Prince act in a drama that requires a wide array of emotions to truly test the limit of his acting skills. The female lead succeeded in annoying the hell out of me - so kudos on that part (if that is what the character requires!). My favourite, I have to say, are the bad guys - especially the two rotten princes. Acting wise, I reckon these bad boys nailed it. I even felt a sense of pity for the prince who kept wanting to "go to heaven" with the doctor because of his health problem and his ambitions. As a modern person, I can sympathise with his need to keep acquiring power and position and thirst for achieving something unique (this bloke can be a great scientist or businessman in this era!). The true evil in this drama, I would say, would be the prince who uses poison- -that bloke is just plain rotten. Once again, the actor nailed that role perfectly! Personally, I would prefer another actor for the role of the king - at least a taller actor. I have issues with men who are shorter or as tall as a woman... does not make them look powerful or important enough... but that's just me! Music: The music is ok. It's not "wow!' but it's ok. Rewatch value: I will not be rewatching this anytime soon. Maybe a couple of years later and I'm bored, I might revisit it. But for now, I look forward to the next new drama. Overall: If you do not have something "wow!" to watch at the moment, this drama is a passable entertainment. Not the best historical, time-travelling drama around... but it's worth a glance.
