Wow! Definitely watch this. There are times where you just hate how ignorant the past is and all the corrupt officials are, but thats what drives the story and the feeling you get when Dr.Jin suceeds is amazing. The characters are so lively and full of emotion even the bad ones. Mind you it does takes ALOT of understanding why each character does an act either of kindness or betrayal, but it is enjoyable. Not to mention the Love-Traingle involved is pretty predicable, but doesn't actually climax till way into the drama. No spoilers but EVERY episode is engaging and supportive to thickening the plot when needed and loosening at just the right time. You find yourself wanting to go back into the past and rewatching this one :D
