Firstly, if you do decide to see this drama, please bare in mind that you should not watch it seriously and be bothered by the logical repercussions of certain actions depicted. I actually wanted to give it a 10 purely on the basis of the ENTERTIANMENT VALUE this drama has but I did not due to my disheartened viewpoint regarding its ending.

Reasons you should watch:
-The Queen (Bong-Hwan) and the King understanding one another and slowly falling in love.
-The perfectly timed comedy that save all the serious moments too from getting overly-dramatic.
-The support cast add a lot to the story and are full of characters with distinct personalities.
-Never not entertaining- there is no dull movement and I would wait each week for this drama to take me by surprise.
-Brilliant modern day references incorporated in the Joseon Era.
-Last but not the least, THE ACTING. Shin Hye Sun does emerge as the star playing two characters with different genders simultaneously but Kim Jung-Hyun does an equally good job! Scenes were they are together- none overpower the other and they seamlessly deliver powerful performances. The entire support cast does an excellent job too.

My one and only complaint:
-The ending. I do not want to include spoilers in the review and so I won’t expand on this but it sort of undermines the purpose of the journey BH and CJ shared as CJ fell in love with BH as the Queen.

The ending might not sit well with you just as it did not with me but I do see people interpreting this as a happy one as well. However, I would still go on to say the show was refreshing, entertaining, comic, surprisingly romantic and worth a watch!
