I saw Children of Men again today, and I am as amazed as I was the first time, if not more so. (Go see it.)
Seated in the theater before the film began, an alternate version of the film's premise occured to me and has been bothersome in my mind all evening. As you probably know, Children of Men imagines a world where women have inexplicably become infertile and humanity seems doomed to extinction after extant generations have passed. A nightmarish scenario, but here's what occured to me: what if the human female population did not become infertile but instead inexplicably began giving birth only to babies of one sex?* This would also render humanity incapable of perpetuation, but it would mean there'd be one last generation composed either exclusively of males or exclusively of females.
I can hardly imagine anything more unpleasant than being a member of the last generation of males. I'd rather die. At best it would be a world of douchebags, competition for the (rapidly aging) females rising to feverish levels until they all died out and only males remained for a few final decades. At worst, human civilization would just quickly descend into an orgy of mass murder. I really believe that.
But what would a final generation composed exclusively of women be like?
*surely this premise must have been treated before somewhere in a book or film. i haven't encountered it; has anyone? and don't say Y: The Last Man. that's not the same premise.
