I've watched this drama a long time ago, and even after all this time there's something about The K2 that just simply remains in the air. What makes this drama taste different is the complex relationship between the hero, lead actor Ji Chang Wook, and the antihero Song Yun-ah. Unexpected. And their acting skills. Superb.
Scenography, storyline and cast are ok most of the time, and impressive on a few occasions, the action scenes seriously well done (lead actor is impressive in combat skills and stunts) and the plot really captivating.
The antagonists in this drama are interesting and well portrayed, but the real magic happens when the hero K2 and Madame Choi take the scene.
As actors, they excelled. On their own and together. The evolution of their relationship in the drama is unexpected, hard to understand at first, atypical.
The character of Madame Choi is something you won't forget easily... If you really understand what's going on. One of the most brilliant antihero out there. Worth watching.
