Wow, I never thought I would like an action movie with an overdose of brutal violence like that, but you have to give credits to a great story, and an amazing cast. The two leading characters, and the story are instrumental in making this movie worth watching indeed. Won Bin, how could he expresses a suppressed anger like that. You can't help but feel his emotions allover the place, even when he is keeping them inside, or act like he is. I wish that the movie would have tuned down the immense violence which was very disturbing, and if I may say, unnecessarily long. Would have loved to see more of the interaction between Won Bin Character and the young girl (actress, Saeron). The scenes between them were pure phenomenal acting, funny, emotional, and heartbreaking. And I would say for their final scene only, you can see this movie more than just once. It was much exhilarating to see Won Bin, at last, releases all his emotions with no hold. Great acting hands down for Won Bin, Saeron, all the villains, and the supporting cast.
