the hero's 'faceless' apartment (bare white, little furniture -- maybe large for nyc, but still a studio -- is this really supposed to be nyc? it's not so clear) -- the 'faceless' unidentifiable streets around the school and the incongruous juxtaposition of the lighting store & the child hooker), the white halls with the stereotypical black ghetto type parachuted into the nearly all-white school -- i think the school is nowhere & everywhere, it's faceless/mix of suburbia/ghetto on purpose, because the story isn't particularly about 'the ghetto' or inner-city schools or material poverty, it's about society in general.
maybe the child is always dressed scantily, that uncertainy in viewing her as child/sexualized because that's the same tension that exists in society, where we talk a good game about sexualizing kids and all are a-twitter about pedophiles -- but the culture at large in fact encourages sexualization of children through various means.
just my opinion. lots of food for thought but i felt some overkill at certain points and some conflict in the subtext.
