I started this drama on a whim, originally interested because I love one of the OST songs. Well, that was one of the best decisions I've made. This drama packed-in so many great things, from music to acting to story, that it has been hard to find another one like it. All of the performances were so powerful, especially that of the king, and really immersed me into the story. And, most of all, I enjoyed the fact that the ending was believable, not saccharine-sweet and not unnecessarily tragic. I recommend this drama from the bottom of my heart - whether you want to learn more about Korea's culture or you just want to watch a solid drama - seriously, watch it, it's worth your time.
