When I first saw the trailer to this movie, I wanted to go see it but wasn't like super hyped up for it. It basically looked like the Korean version of "LEON: The Professional". But this movie is like the Korean version of "Man on Fire" with fight sequences that are similar to the "Bourne" movies. I heard this film really skyrocketed Won Bin's popularity, especially in Korea and I could tell why. He really is a badass in this movie and his charisma is overflowing in this movie. One of the girl in the audience couldn't help but say "he is so cool" in Korean during the scene where Won Bin's character is driving angrily while on the phone with the bad guys while showing some intimidating emotion. The plot isn't super original or anything, basically "Man on Fire" with a better flow and more dark and gritty with better action in my opinion. Overall this film was a lot better than I expected and also kept my interest from beginning to end while also being entertained. The style of this movie reminded me of "A Bittersweet Life" in a good way which is a plus with saturated colors leaning towards the dark and blue. Some people might get a bit irritated by the constant camera shot to Won Bin's face while he takes a pose like in some magazine or something. But I could tell it's to sell the movie to female viewers as well. Excellent casting, pretty good story with some slick action scenes make this movie really worth seeing, there is something for guys and girls.
