How could Michael allow Vincent to take over? I mean, fair enough Andy Garcia did a good job with him, but he was no Don. Surely Michael could have found someone slightly more subtle, even Al Neri would be a better choice I think if he couldn't find a blood replacement. He was exactly like Sonny, couldn't Michael see that he'd destroy the family, he's supposed to be shrewd and intelligent. Maybe he was slipping in his old age?

I mean:
"I say we make em dead! You give the order, I take care of it!"
