I really disliked the fact that Michael "passed on " the power of the family to Vincent.It was not a smart move and it just seemed "out of character" and lazy for Michael.As for my answer to this question: i believe Tom would have disapproved. Who do you think that he should have passed it on to? Tony Soprano
