As much as I love the Zero Woman series (and I do, in spite of my friends and relatives' scorn) I gotta say this latest entry is just howlingly BAD.
The plot is confused (there are two -count 'em- female assassins in this movie and for quite awhile it isn't very clear who is who, and more importantly, why?). There's a lot of shooting, and some bad American soldiers (Americans seem to be on the side of the bad guys here, as if they were still, in 2010, an occupying army), some student revolutionaries who are mad about something, and given to laughing fiendishly, what looks like a Catholic priest who seems at first to be a victim but later seems like a hero, but he killed himself for some reason. There is flickering love interest between the new Rei (Zero Women are all named Rei) and a naive young cop who stumbles into her business and won't go away, until he gets offed too, and so on. The sex scenes (mostly with the other, bad female assassin) are, in fact, almost completely gratuitous, filled with nasty slurping and lip-smacking, and often have a grainy, poorly lit look, like out-takes from a cheap porn movie... Which this movie sort of totters on the edge of becoming during these extended, boring scenes.
It's not even clear at the end of the movie whether Rei's boss has shot her... or just shot AT her in exasperation. Is she dying of a bullet wound, or just feeling kinda sad about all the pointless sex and violence that she's had to wade through for the last 90 minutes? We'll never know, because the screen abruptly slams to black, then credits.
The only remotely good thing about this film is the truly awful (and occasionally hilariously awful) subtitles - the worst I've ever seen - stiff and literal at best, absolutely impenetrable at worst! Even if, like me, you were at first delighted to see that Zero Woman is not dead and gone after all (the jacket says "She's Back With A Vengeance!"), give this one a pass and save your money! If the franchise can't do any better than this, I'd say put Rei to rest at long last. I was so disappointed. The tears are dripping on my keyboard.
