This show was pretty close to a masterpiece. This is definitely the BEST drama I have seen so far. There are hardly any complaints from this show. The story line and plot are excellent. I love the whole setting of the Joseon era. It provides gender bender in a whole new perspective. This show is the first ever gender bender scenario I have enjoyed thoroughly. The show has an excellent cast. I am a very big fan of Park Min Young. She was the one who stole the spotlight as Kim Yon Shik. I have NO complaints when it comes to her character or any others. I think this show is the best I have seen in any language which has such great, over-the-top characterizations. Everything has to do with outstanding writing. Maybe it has to do with the fact that they are all scholars, but it absolutely brilliant. It has the perfect female, perfect male, perfect antagonists and perfect second and third leads. The actors are equally good who have played their characters so very well. I rate them full where acting is concerned. The direction seemed to be a bit clumsy at places but considering that this is a periodic drama I have to pat the director's back for the phenomenal settings. I almost felt like I was part of the Sungkyunkwan. I would love to meet such brainy scholars. The show had so many cool riddles that I liked it. Also, they seemed to have used heavy and formal language while speaking. I liked that too. Not just the lingering mysteries and sub-plots, I was happy with the humor. Every episode had very funny moments, most of them consisting Geol-Oh and Yang Ha. Also the episodes where Lee Sun Joon is attracted to Kim Yon Shik and thinking he is a homosexual were very funny. I really loved the spirit of Kim Yon Hee. She is also one of my favorite fictional characters from tv shows now. I am not fond of females that are pushovers or without pride in stories. Anyway, this show makes me hungry for more periodic dramas but I don't think any other one could be as good as this one. I would recommend to everyone who is searching for a no-nonsense drama.
