OK, this is obviously a setting where the theme is all-important, so it feels churlish to talk about realism, but at this point I just can't look away from questions like, why are they just sending pairs of young teenage girls into the city to find their own, um, blood donors when vampire hunters are a thing? Even if they're supposed to learn how to do this stuff, shouldn't there be older, experienced, heavily armed vampires on overwatch?
