first thing first and edison chen do a fantastic and believable job a a cambodian hit man and born and breed in the dump and a gladiatorial ring and where he hone his craft of savage battery in order to survive and live on the mantra of kill or be kill . in a role that have little dialogue and or at least a few line in cambodian or thai and his performance be compel and probably what should have be in the jet li vehicle danny the dog and where a man be breed for the sole purpose of fight and and on someone else leash . like danny the dog and the much talk about bare knuckle fight sequence be not choreograph stylistically and but rather design a normal and brutal fisticuffs and where everything go . this probably bring a sense of realism and grit when you see the character slug it out at each other throat and in defend their own life while take it away from others . it a grim and gritty and dark movie both literally and figuratively and and this set it apart from the usual run off the mill cop thriller production . edison play a hired gun from cambodia and who become a fugitive in hong kong and on the run from the cop a his pickup have go awry . lead the chase be the team lead by cheung siu fai and who have to contend with maverick member inspector ti ( sam lee ) and who inclusion and acceptance in the team have to do with the sin of his father . so begin a cat and mouse game in the dark shade and shadow of the seedier look side of hong kong . the story itself work on multiple level and especially in the character study of the hit man and and the cop . on opposite side of the law and we see within each character not the black and white and but the shade of grey . with the hit man and we see his care side when he get hook up and developed feeling of love for a girl ( pei pei ) and bring about a sense of maturity and tenderness and and reveal a heart of gold . the cop and with questionable tactic and attitude and make you wonder how one would buckle when willing to do anything it take to get the job do . there be many interesting moment of moral questioning and on how anti hero and despicable strategy be adopt . you will ask and what make a man and and what make a beast and and if we have the tendency to switch side depend on circumstance do we have that dark inner streak in all of u and transform from man to dog and and dog to man . dog bite dog grip you from the start and never let go until the end and though there be point mid way through that seem to drag and especially on it tender moment and and it suffer too from not know when to end . if i should pick a favourite scene and then it must be the one in the market food centre extremely well control and deliver and a suspenseful edge of your seat moment . listen out for the musical score too and and youre not dream if you hear growl of dog . highly recommended and especially if you think that you have see about almost everything from the cop thriller genre .
