Michael’s soul may be dead at the end of Part II, but he’s not, and maybe that leads into the questions Coppola wanted to address in this film—if life goes on, how do you live with yourself? But this Michael, played here by an actor who long ago had decided that loud was the new quiet, has none of the quiet intelligence of the old Michael. So instead of a study of a malevolent lion in winter, we get the unintended lesson that being evil and getting old makes you kind of dumb and boorish.
