I don't think it's fair to label this movie a sequel to The Godfather. The two complement each other perfectly and are more of a companion piece to the original. There is a prequel and a sequel to it, showing the rise of Vito and the moral decline of Michael. Al Pacino and Robert DeNiro play both characters with uncanny ability. A nuclear bomb makes a loud noise, so describing these two actors as good actors would be like saying that they are at the top of their respective crafts. It is fascinating how Al Pacino's eyes have changed since the first part of the movie. He is the star of the ensemble cast. They are now cold , ruthless and unemotional. They betray the price that Michael Corleone has paid for power. Watch this movie and learn why it is the greatest gangster film of all time.
