Sasha Baron Cohen's alter egos get a chance to run rampage in the good ol' US of A, and while Ali G feels like something of a spent force, Borat from Kazakhstan and Bruno the camp Austrian are still managing to behave like idiots but, importantly, make everyone they come into contact with look considerably dimmer. While Cohen continues to ridicule and satirize sections of society who deserve every verbal kicking they can get, this doubles up nicely as comedy and public service.
