I think the first about 35 episodes were really good. I really enjoyed the gender-bender tropes in the beginning with Ki being a warrior and a rebel and all that. But then that was completely taken out of the plot, which I wasn't terribly upset about, but at the same time, I missed it (gender-benders are a guilty pleasure of mine haha). And then around episode 35, things started to slow down a lot and a lot of the plot devices started to be reused (for example, poisoning, assassins, characters dying, but surprise!, they miraculously survive!, etc). And I think what made the whole drama completely unsatisfying in the end was the fact that the Emperor of Yuan (played by Ji Chang Wook) was a complete coward and extremely unlikable as a person. And while the Emperor of Koryo had his flaws, it was tragic that he and Ki couldn't be together due to the shitty circumstances.

~~~~~~~~SPOILER AHEAD~~~~~~~~~Read with caution!!!

Before starting this drama, I spoiled the ending for myself because I saw the "tragedy" tag; originally I was okay with the ending where Emperor of Yuan dies because then I figured that Ki could then have her chance with the Emperor of Koryo now that he was out of the way, but THEY KILLED OFF THE EMPEROR OF KORYO IN LITERALLY THE LAST 1.5 HOURS OF THE DRAMA. WHAT IS THIS SHIT?! They also killed off Yon Feisu, who I thought was a complete bad ass - her death really ticks me off just based on principle. And they also killed off Tal Tal who I adored - I'm kinda salty about that too. ???? (I really think that Tal Tal and Ki could have had something special between them if given the opportunity...)

And let's just be honest - the Emperor of Yuan was a piece of crap. He wasn't a man, his character had no true development, and he was just a pain to watch. All the decisions he made were foolish and self-serving, with no regard to what was best for his people and/or his reign. He didn't *love* Ki. He was obsessed like a psychotic person and literally made decisions to mess things up based on spite and jealously. How pitiful, childish, and annoying. I saw clips of Empress Ki that got me interested in watching it and honestly, they were completely misleading. There's nothing cute or loving about the romance between Ki and the Emperor of Yuan. This story truly is a tragedy, so if you're thinking about watching it, bear that in mind.

I know I'm harping on some stuff really hard, but it *was* a decent drama, but I just wasn't happy with how the writers handled the characters in the last 20 episodes or so and the ending. I was okay with there being sadness, but I don't think the tragedy was expertly written and so it left me feeling very unsatisfied and bitter. Definitely not a rewatch for me.

The actors in this drama were truly great -
Ji Chang Wook has always played quirky characters and he really did well portraying such an insecure and petty character.
I've tried to watch Secret Garden and Kings2Heart with Ha Ji Won and I wasn't impressed with her acting very much, but I think she did a really good job here. Not enough to make me an avid fan, but truly surprised at her performance.
Kim Ji Han grew on me. He's not conventional handsome, but man oh man did his acting grow on me. I think I'll try to pick up another drama with him to see how his acting is in another role. His voice is soooo sexy and he has definitely mastered the smolder. XD

I will also say that the OST was very good. I didn't get annoyed with any of the songs and the song selections for each scene were very well placed.
