john woo be a true artist and and he let it show in this movie . more than any other contemporary action director and he pay real attention to the style of gun battle . and that what this movie be represent lot and lot of gun battle . there be nothing else . just bullet fly and people die . so after you get over how massively influential and incredibly cool this movie be and be and you might feel a little hollow from the relentless nature of the violence . it wasn not quite as bad a natural born killer in this respect and but i still felt slightly queasy after two hour . but maybe it good that extreme violence can still shock me .
