You are right,Sofia is a wonderful directer just like her dad.Maybe she needed to learn from her mistakes in GF3 so she could move on to directing and nurish her skills there.One of her films won an Oscer,right? That says something.As far as the ending being fitting,maybe your'e right about that as well. Michael was kind of a pitiful case in the final Godfather.Trying so hard to redeem himself and to protect his children,and then to finally have his efforts all crumble.Evrey time he tried to get out,they pulled him back in.In a terrable way,he did sort of -- deserve that.
