"Godfather"part one is a better movie than "On the waterfront." After reading Mario Puzzo's novel and seeing the movie, I personally did not find necessary to follow the Corleone saga in Godfather part 2 and 3. However, part one shows an incredible portrait of Cosa Nostra, you can't help but enjoy the vilains. It is a credible film, with strong performances of all the male leads, Brando, Cazale, Pacino, James Caan and Robert Duvall. The pacing, the script, the dialogue, cinematography represent for me top quality. It is indeed even a better film than "On the waterfront".
