Yes, I could never figure out why they didn't have Anthony or one of Sonny's boys go into the business. It would have been more interesting to see Anthony give up his career and become like his father. Vincent sort of just came in as a stranger to the entire audience and didn't seem part of the family.
I also found the storyline between Vincent and Mary, his cousin kind of disgusting and unecessary. That made the story and Vincent even less appealing to me.
