The story line is excellent but somehow it felt that Vincenzo is fixing the target of a case who is corrupt and working for Babel, threats him with his life, tortures him and along with evidence gets the work done to bring down Babel. This happens all the time so it becomes a little boring. I very much liked Ok Taecyeon's acting, I actually really appreciate his two-faced acting. However Jung Han Soek seems to be nothing in front of Vincenzo and his plans, if their fight have been a little more neck to neck then it would have been perfect.
Next the protagonist Vincenzo and Hong Cha Young they started to become more cruel like torturing people which is just thousand times painful than killing them in one go. And I lost interest while watching tortures. They are just doing some cruel acts in the name of justice. Nonetheless cinematography is very exactly created.
