Parts I (1972) and II (1974).
A mournful tone segues into the familiar large family gathering, a setting wherein the current Don is lavished with honours and respect. His move into more legitimate business affairs gives the film a different kind of edge, but it's one that's dulled by a screenplay that feels stretched thin. In addition, the appointed successor to the Corleone name is never fully able to step out of the shadow of the characters/actors that came before. Even when considered as a counterpoint, it's not as satisfying as it could've been.
Pacino and Shire are great (and for the record I don't think Sofia deserved the criticism she received), but the highlight is the superb finale, staged at an opera it is itself a beautifully orchestrated piece of pure drama.
