"“Us” highlights the unwitting complicity of even apparently well-meaning and conscientious people in an unjust order that masquerades as natural and immutable but is, in fact, the product of malevolent designs that leave some languishing in the perma-shadows. (Designed by whom? The movie doesn’t name names, but it winks and nods and nudges in a general direction that runs from the sea to the lake.) It dramatizes this world, but with a twist—one that (avoiding spoilers) risks overturning conventional values and sympathies with ecstatic fervor. Suffice it to say that “Us” reserves empathy for its unwitting villains while gleefully deriding their comfortably normal state of obliviousness—and the ordinary absurdities of the world at large."
