Enjoyed this drama very much. It tells an amazing story- an arduous but worthwhile journey to realize a larger dream. The characters are great. The cast is brilliant. Each one of them- good or bad,even the irredeemable ones, stand out in our minds. It's hard to say what I feel about the drama without giving spoilers, because there are so many great moments, conversations and scenes that come back to me now. Suffice to say, there's more than one hero in this drama and many memorable characters. King Sejong is a great king, more human than any Sageuk king I can remember having watched. Chae Yoon is our hero, and he stays strongly in character until the end. The most charming part of the drama are the many relationships it shows- between King Sejong and Moo Hyul(great rapport, even cute at times), King and Chae Yoon, King and the girls, Pyung and Jung Gi Joon and so on. One thing you shouldn't expect going into this drama, though, is romance. There isn't much or any really. A hint of it comes from Chae Yoon, but isn't built up or even entertained beyond that. Our lady, So Yi is smart, emotionally strong and with a very capable head on her shoulders, but her devotion all falls on her King and her cause. There isn't time or space for anything else. But it doesn't matter really,as viewers, because.. it's all about great story telling and this is a sageuk everyone can watch without getting bored at any point.
