Part 3 was as horrible as Parts 1 and 2 were outstanding. Of course part 3 was re-written at the last second as Duvall refused to participate because he was terribly low-balled on salary.
Part 3 could have been the best. It focused on Duvall’s character Tom Haden who was murdered in the proposed movie. Three parts, three brothers murdered, each in their own episode.
In the end, there was only Michael living, the one who wanted nothing to do with the family business.
A friend of mine makes the point that the movie isn't all THAT bad, and if it had been called something other than Godfather 3, and the characters had all had different names, it would be looked at in a much more favorable light as a solid mob melodrama.
It was embarrassing, watching Pacino in that role. And I can only imagine how humiliating it was for Andy Garcia to play opposite Coppola’s untalented daughter.
