Excellent police/gangster action thriller. Dong-seok Ma, in the lead role was flawless and delivered the funny dialogues superbly. The fact that this was based on real life events, makes in more intriguing to watch in every sense. Kye-Sang Yoon on the other side of the law manages to "UP" the hate factor for the bad guy with his portrayal of the violent head of the Chinese gangster-invader. All round first class action flick!
