Here's the problem with THE GODFATHER, PART II: it doesn't add to the story of THE GODFATHER. Michael ends THE GODFATHER well and truly damned. By the end of Part II, all he's done is find out what hell's like. Vito ends THE GODFATHER a man of honor, by his own lights. That's how he ends here. There is nothing that happens in Part II that hasn't already been done, and done more elegantly, in the original.
So why is it so riveting? I believe that Part II's performances overcome its screenplay. Al Pacino's Michael Corleone is so interesting that I don't mind that all his character does in this film is live out the consequences of his earlier choices. Diane Keaton's Kay Corleone is so heartbreaking that I nearly wept for her. Robert Duvall's Tom Hagen is the most scarily efficient man I've seen in film in a long time. And Robert DeNiro's young Vito is everything we might have expected young Vito to be: cunning, brave, charismatic; a man who commands respect.
It's damn hard for actors to rise above their source material and bring real art from mediocrity, but this cast pulls it off. They're what make watching THE GODFATHER, PART II time well spent.
