I think it came out the same summer as The Matrix did and Bale wasn't as big a name as he is now with American Psycho being his only big American movie credit. Admitedly, The Matrix is a much better movie over all and so it basically got its thunder stolen as being the other kungfu in the future movie that didn't advertise as much and called its fighting the decidedly lame name of GUN-KATA.
*shrug*
It's an alright flick if you haven't seen it before. It's at least as good as say, V for Vendetta though it's strengths lie in different areas. One of my favourite things to nitpick about it is the simple fact that no one is suposed to be allowed to show emotion in it and one of the main plot points is this whole thing where everyone is watching Bale all the time and he has to look like he has no emotion even though his is actually really pissed off and scared, and etc. Well the whole movie, everyone who isn't Bale fucking shows emotion all over the place! The big bad shows anger readily and his henchman is fucking laughing it up and smiling all the time, so who the fuck are they to claim Bale is a feeler? They really fucked it up, basically. Good fights though.
