When you get a story written quite this magnificently it would take an extreme amateur to screw it up - and Francis Ford Coppola is no amateur. Marlon Brando, Al Pacino, James Caan and Robert Duvall represent the epitome of guile, sophistication, loyalty, honour and brutality in this self-adapted Mario Puzo story of the unambiguously ambitious "Corleone" family - they start with nothing and so the only way is up; however and whatever they need to do to get there. The characterisations are layered and colourful; Diane Keaton has no idea what she's getting herself into! John Cazale is great as the spineless brother "Fredo" too. Once again, Nino Rota pulls out all the stops to give this a score that helps cement this film's place as amongst the best ever made. My only criticism, and it is slight at that, is that the audio mix could have done with a bit of a boost. Much of the dialogue - especially from Brando - verges on the inaudible at times.
