District 9 (2009)

The aliens have arrived and been confined to a settlement outside Johannesburg, where official language makes exploitation sound administrative. Neill Blomkamp's mock-documentary framing lets a bureaucrat's routine become an increasingly personal crisis. The social premise gives the grotesque transformations more force than a simple invasion plot. It is an abrasive, violent choice, and its broad caricatures deserve scrutiny alongside the more persuasive argument about dehumanisation.
