I'm really into this at the moment. At first episode I was like: what the hell am I watching? But I enjoy it all the way. I like that the characters are not so typical as usual. I absolutely love the ruling couple- they are adorable. The Doctor is great because she's not you typical drama-lead damsel in distress - she's really smart and independant character, I like how she uses her 'heaven' references in contacts with others. And the General.. Lee Min Ho- why are you so perfect to play a hero *faints* ... I like the moral simplicity and faithfulness of his character, and that he's not easily swayed by others. And first I wasn't so sure about the chemistry between the leads, but now I see it, for me it's a deeper and more mature relationship developed from mutual trust and tenderness, it's quite refreshing and different from typical "I hate you, but I love you" type of story.
I also enjoy all those unusual side characters- woodalchi, parkour guy, street gang, doctors, herbalist -it gives a bit of magical atmosphere to the story.
Eh, why there are so few episodes left.
