This movie is totally crazy. It is about mobs and revenge. There is no sweetness at all. Once Tae Soo starts to take revenge for his twin, Tae Jin's death, it is amazing. Ji Jin Hee's character Tae Soo is an assassin, but he isn't typical. He doesn't seem to have the stealth or finesse that you usually see in a movie. He also doesn't act like he isn't in pain when he gets hurt. It is refreshingly real. The action is gruesome. If you aren't into that, then you probably won't enjoy this movie. If you are the type of person that likes revenge stories, then this is a drama that you would enjoy.
