I think what fascinates people with the idea of making a godfather 4, is the simple fact that it would be better than most of the crap that's churned out right now. For God's sakes they gives us Ocean's 11-2011 but they can't figure out a Godfather 4?!!!
There is no guarantee that it would be better though. And imagine if it would be worse... Part III takes a lot of heat and I don't even think it was that bad. Yeah, compared to perfection even good movies feel flawed, and that's what happened to Part III.
But the difference between the GF and the Ocean's movies is that all the characters are still alive. That series never had what was supposed to be the definitive end to the series like the GF had. So it doesn't feel like much of a stretch when they make an Ocean's sequel or a sequel to any other Hollywood franchise nowadays?
