I read a few of the other reviews before I decided to post and I don't fully agree with them. Yes this is a sageuk (historical k drama) and yes it is long. 51 episodes may seem like a long show to watch but it is well worth it. There are of course artistic liberties taken with the story but the traditional story line is still there and this drama also does a good job with costumes and period accurate details. It keeps you on your toes and its not just a happy go lucky show, there is real drama and real suspense. If you can find the time for the whole drama you will not regret it, the characters good and bad make you love them. The lead female is powerful and impressive while being elegant. Leading men both pull off their characters well and while you will most definitely find your self screaming at the screen during this drama, its ability to frustrate and suprize its audience is one of the keys that kept me watching. On another note if you are interested in history or in Asian culture this drama is intriguing and can give you new insight without being opressive. I don't want to add any spoilers so I am going to have to stop here but as a last word this is my favorite sageuk and I recommend it to everyone. ***re-watch value is only low because it is long.
