I seldom watch historical drama, But definitely this one is worth watching . I've been watching K & C drama. and this one of the best. Jung Il woo is a great actor he definitely one of the best on his generation. I watched all Jung Il Woo's drama and this one he is more mature and acting is superb. The supporting cast are all great, Go Ara is just OK but tolerable unlike Hwarang

Don't hesitate just watch this great drama. You can feel that you are living in Joeson Era, You can feel the emotions specially when the king are talking to his people, you can feel the love and care for his countryman.
