Where Blomkamp's political subtext fails is in its lack of follow-through. Max is not a political actor. His motivations are strictly personal, first self-preservation and then the preservation of Frey's daughter. And the conclusion wraps up so neatly, as to suggest all the problems of the world are strictly just as personal, and not the consequence of decades of structural inadequacies.
"Elysium" will delight the eyes, but won't be changing hearts and minds. It's simply another round of summer popcorn fodder.
