It's a frustrating movie because there were just a few things they could have changed to make it great.
Connie. Connie in my opion had way to bigger hand in this film, being in the sit down with Vincent and Zaza, making decisions on clipping people.. Her singing in the beginning, her quip with "Will somebody please hail mary" in front of the bishop..
Many of the flaws that have been pointed out here are valid ones. However, when it comes to the Connie character, (yes, there were a couple of Cheesey lines on her part) Talia Shire actually was the best in that she was able to complete the way that her character morphed from this innocent abused little sister in GF to a revolting and defiant sister at the begining of GFII, finishing up as the matriarch of the family who did what ever she could to try and save the Corleone family by the end of GFIII.
She gets my vote as 'comeback character' of the trilogy!
