Let's face it, folks -- not only should there not be a Part Four, there probably shouldn't have been a Part Three either. The story was complete enough after Part Two, with Michael alone with his ghosts. Part Three, with Michael in a "King Lear" phase, is a noticeably weaker movie. It was released before Coppola was really ready, and unfortunately that's obvious when watching it; you get the feeling it's ALMOST great, but with some work it could actually BE great. (Perhaps Coppola could go back to it some day and do it the way he really "wanted" to, as he has recently done with "Apocalypse Now.") I agree with those who say there's too great a chance that a fourth installment would be hugely disappointing, even if Coppola directed (he's pretty inconsistent).
