I think Vincent wasnt too bad, But I would have much liked more to see one of Sonny's real sons take over the family buisness like Frank or Santino Jr. This would have gave the story a little more eliment and would have been less confusing. I also didnt like the fact that Coppola let his daughter play such an important role, It kind of makes me a little sore at Coppola for doing so because I beleive part 3 as a whole could have been so much better without the bad acting of Mary. The plot itself for the movie wasnt too great, I wasnt feeling the whole big buisnesse's and chruch ordeal, all very confusing. Part 3 either should have never been made or should have been something else completely, like part 1 stay the same, part 2 be all about Vitos rise to power and the Corleone children growing up, and part 3 be like Michaels scenes in part 2, all about him in Vegas and being a ruthless Don and the very end of the Trilogy would just be him sitting lonely with all the memories of his past. Would have been CLASSIC!
