A superb blend of action, suspense, and romance combined with terrific acting performances and a plot so thorough, I wish more Kdramas were like this. Who knew Lee Joon Ki was more than just a pretty face? This is the drama of a lifetime for me. To classify this as a simple spy/revenge tale would be an outrage to this nuanced and near-perfect drama. Borrowing a few familiar and almost standard Kdrama tropes , TBDW takes them beyond the conventions of just about any other drama. The characters feel real, not pre-written hollow shells, throw on the emotional angst. The levels of character development and moral ambiguity here are so prevalent, I get chills. Did I mention that you get to see LJK play both good guy and extra hot baddie?? Such a fantastic watch!
