this film be wonderful . although slow in place and this thing be a work of art and beauty . andy lau be amazing and dynamic and charm . i really enjoy the multicultural aspect and and felt the tension between character a their individual mystery unfold to be very charming and sincere and often surprisingly touch . in an rather tired and often exploit genre and this film really stand apart a an example of the value of depth in character and theme and story no matter how two dimensional the track story might be . the making of footage on the flip side of the dvd be equally nifty and because seldom will a film include multiple agonizing take of key scene both action and non action so that you might understand how excruciatingly demand and exhaust film making can really be .
