This is certainly one of my favourite historical dramas that I have watched so far. 50 episodes might sound tiring to you, as it did to me at first, but after watching even the first few episodes of this drama, I found myself glued to the seat, wanting more, and now I can't even wait for the new episodes. Every episode is so intense and full of emotions (though sometimes I do feel the shouts are a bit annoying). I also have to say the background music and songs just add more to the feelings. Great cast, great acting, great music and overall, a well-written drama (at least, so far). Highly recommend this to those who love Korean Historical Drama. It will never bore you.
