This Drama was heavy, heavy, heavy. For a sageuk themed drama, with the glamour of a King and his followers... this had a fantastic story to tell. Before checking this out, you, the viewer need the proper mindset before committing yourself into watching this drama (unless you are already into this kind of drama). Why? Because this is too far away from being romcom or light. There are witty scenes where you find the "funny" but not so much, because it would be obliterated in a second by the realism of the situation the characters are in. Watching this drama was heart racing, mind boggling and most of all tear jerking if you get to finish this in one go. It was also frustrating being in the perspective of the king - because a person with so much wealth and power could be so helpless at the same time. *sigh* My favorite character here was King Sejong - Han Seok Kyu's portrayal of him was so convincing that my heart was moved every time he does or say something. His decisions throughout the drama was really something, because it amounts to the lives that revolve around him, one mistake means the death of someone and one right thing could lead to the abundance of the entire nation. His role was really something and his acting was so deep into the character, I tend to forget that he was only acting about the agony of a king who cherished his people. Then here comes the King's person: Kang Chae Yoon and So Yi. These characters were portrayed by high fantastic artists - Jang Hyuk and Shin Se Kyung. Their roles were vital and important for the success of the king's plan and well... the ending was very dreary but there's that sense of fulfillment despite everything they have gone through. All in all their characters made this drama an unforgettable one. The music isn't that catchy or is something that would stick to your head forever, but it does add to the drama. As for the re-watch value, I would not want to re-watch this lest I want to depress myself or stress myself all over again, but over all this drama is still dear to my heart. I loved this drama and would highly recommend it to those who love watching sageuks involving historical documentations. Tree With Deep Roots - will move you, haunt you and make you change your outlook about your given language. Because this drama depicts history and the people who sacrificed a lot to make things possible.
