It would have been educational though.
I'm not sure which of Godfather and Godfather II is better - they are both utterly magnificent.
One thing to avoid, if you haven't seen them, are any 'chronological' versions, which take the prequel sections of G2 and put them before G, then have the sequel sections of G2. The BBC has shown this at least once. Part of the greatness of G2 is the way it contrasts and cuts between the two parts of its story, and separating them out diminishes it.
