"Taxi Driver" is the definitive cinematic portrait of loneliness and alienation manifested as violence. It is as if director Martin Scorsese and screenwriter Paul Schrader had tapped into precisely the same source of psychological inspiration ("I just knew I had to make this film," Scorsese would later say), combined with a perfectly timed post-Watergate expression of personal, political, and societal anxiety. Robert De Niro, as the tortured, ex-Marine cab driver Travis Bickle, made movie history with his chilling performance as one of the most memorably intense and vividly realized characters ever committed to film. Bickle is a self-appointed vigilante who views his urban beat as an intolerable cesspool of blighted humanity. He plays guardian angel for a young prostitute (Jodie Foster), but not without violently devastating consequences. This masterpiece, which is not for all tastes, is sure to horrify some viewers, but few could deny the film's lasting power and importance. "--Jeff Shannon"
