Is it possible to make a more depressing end to a movie than the end of Godfather part3?
I think not.
That`s the best reason to make a Godfather part 4.
And let it have a happy ending.
Vincent Marcini finish off all his enemies in the underworld and reaches the top as a happy and rich businessman, with a happy family.
Of course he needs to kick lots af ass.
He needs to kick the shit out of all the other families as well as some new russian mobsters along with some assholes from Columbia. But that`s gonna be fun.
When it`s all over he is a respected and loved Godfather in the legal world and feared by criminals.
The Corleone family needs to live on.
