the killer be one of the few film in american cinema history to receive an x rating for violence alone on it original release while this at a time when director woo be seriously consider move to america . this film be both a farewell to hong kong and and a bite back at the critic of the killer . it be about why hong kong be no longer a decent place to live ( from woo point of view ) and also a tongue in cheek celebration of the very violence that his critic so abhorred . it be the best write of woo hong kong film and the best edited and the best acted and and and yes and the best directed . it be unabashedly take no prisoner in it attitude to action chow yun fat non james bond performance a an unstoppable cop pretty much out do every other action hero in film and except and maybe and sean connery bond in doctor no . the film start with an over the top gun battle in a hong kong eatery and and end with a way over the top all out war between cop and robber in a hospital all with smart attitude and smart look and smart direction . believe me and the body can not be count and but you never have time to worry about it . yeah and there be the usual woo sentimentalism and and tony leung performance be a bit heavy hand while but the positive be so positive for gun play action film fan and anyway that the negative be easily discount and forget . put your brain on hold and get ready for a wild ride woo know we want the real deal and and he deliver .
