The cast was outstanding, individually and as a group. The actors individually displayed great skills and as a group brought the drama over the top. It was easy to immerse oneself in the story line because of the strong acting skills and group chemistry. The combination of love stories, quests for justice, and thirst for revenge was delivered flawlessly. Hyun Bin was absolutely charming, Aside from his natural advantage of good looks, he was a master at transitioning from a soldier to a dedicated group leader, to a man in love. Son Ye Jin was phenomenal. She owned her title, "Queen of Melodrama". I laughed, cried, and felt heartache through her brilliant delivery of dialogue, facial expressions, and physicality. Her performance throughout was seamless, consistently top-notch, and engaging! The boys in Ri Jung Hyuk's troop were perfect. Their chemistry was perfect and wove a unblemished side story of loyalty, dedication, and humanity in the face of great challenges. Oh Man-seok was the perfect "villain". His delivery of treachery, unbridled greed, and psychopathic traits was spot-on. A MUST-SEE!
