The first thing that came to me upon reading the synopsis was like..." a ghost in a sageuk is kinda cool." So I gave it a shot...besides Yoo Seung-ho looking like a real GOD of heaven; I'm also curious about Lee Joon-gi. I read sooo many reviews about him being a good actor, and so since, this was his first project out from the military, I decided to try it out; and I'm not sooo disappointed at all!!!! What attracted me most here is the plot. Of ghost wandering around finding her true identity. I am used to watch sageuks in a very SERIOUS manner and I think this gives a fresh plot to those who doesn't watch sageuks too much. So, in Joseon period, there are people around who can see what other people doesn't normally see, is another plus for me. I think, this kind of thing is a bit taboo since it was in the Joseon era. That kind of plot wasn't fully explored, until this drama came out. My curiuosity to Lee Joon-gi lead me to prove me that HE is one of the best actors out there. He bought balance to the story and did "enough" for his role. I know he can play the character better, but I think the story just asks for that much, and its a good thing he played it just way iot should. SHIN MIN-AH is did a very good job here, specially the stunts in Episode 1, and she immersed herself in the role perfectly. She made me laugh, and she made me cry. That's more than enough for me to commend her in this drama. The only character that balances everything here is Yoo Seung-ho. Besides looking beautiful, he did a fairly good job on being the one who knows the faith of two characters. I didn't find any lame characrter here. Every character is important for the story be effective. GOOD JOB!!!!!! :)
