Because Roth is an existential misanthrope, Justine faces the worst nightmare of any privileged white protagonist with unexamined racism in their hearts: an inhuman tribe of flesh-eating cannibals who behead, gouge, impale, drug and devour any outsiders unfortunate enough to cross their paths. "The Green Inferno" is, in that sense, not so much a knock against Occupy Wall-Street-style slacktivists (though it is also that) so much as it's an accomplished, mean-spirited horror film about a heroine who is too young to understand the motives for her do-gooder idealism.
