Ghost Dog: Way of the Samurai - one view of how a street samurai would operate, not a bad little movie either
New Rose Hotel - a movie with problems, but interesting story (based on William Gibson story) with corporate competition, seduction of research assets, betrayal, etc.
Dark Angel (tv series) - varied between cheesy and half decent. Street samurai, genetically enhanced humans, freedom-fighting cells, plus a young Jessica Alba! "By the way, some of those black-helicopter storm-trooper folks stopped by, asking about a transgenic teenage killing machine. I said you were out.", heh.
