I saw this film as one of my free rentals back when I worked at Blockbuster in 2003-2004. I re-rented it several times.
Anyone who enjoys anime, live-action fight scenes, assassin for hire plots, interwoven science fiction plots, subs OR dubs... will love this. The dubs, while not matching exactly, went to great lengths to get the same feel and did wonderfully. The fight scenes are exceptional, and the science fiction elements are perfectly woven in with an assassin-esk storyline.
If only I could find this online somewhere to watch with my teens, they'd love it just as much.
