Sacha Baron Cohen's most effective, nuanced and incisive satire on bigotry: his candid skill at exposing regressions within Western society, by playing the fool in order to reveal the contemptuous core of the candid observer. Whilst his other films feature some hilarious gags, his eye for political savvy has never been more potent.
Divorced from its overhyped and clichéd context (which, as a pretentious teenage fan of the show, I resented), this is a performance art movie, so soaked in blasphemy, truth, piercing satire, and nihilism that its very existence is literally unbelievable. That it went on to become an enormous hit and cultural touchstone is both logical and one of the strangest parts of American film history. A genuine masterpiece.
