It has a promising premise. Unoriginal yes; this sort of thing has been done before (there's at least one grindhouse movie with the same setup) but one of the things graphic novels do best is to tackle tough ideas and make an awesome story out of them. From vikings (the Northlanders series) to cyberpunk (the Gibson adaptations), comics are often the first to take a concept and do it right. I think the writers of Y really half-assed it here. Now that all the men are dead, the strongest military in the world is the Israeli; the strongest navy, Australia. Democrats now hold an overwhelming majority, and food production was hardly affected. Interesting, but hardly revelatory; you're not touching on half the issues you should be if you want to flesh out the storyline, which is bonier than the unengaging protagonist.
