Based on plot & acting and execution, this is in my top 3 favorite dramas. Uhm Tae Woong is a master actor, and really knows how to pick his roles. He mentioned he only picks roles that mean something to him, and it shows. (see Resurrection). The drama is a thriller from start to finish, with no dragged and out of place parts at all. If you've loved Resurrection, and generally enjoy plot-based, action-thriller dramas, this is for you.
