Michael Franzese spoke about the sopranos recently. He said it’s highly unrealistic because the boss would be killed for seeing a therapist. But that’s the point of the show. Tony knows he’s taking an enormous risk by seeing a therapist and there is even an attempt on his life. He had to eliminate his rivals within his own family. I think Silvio was really the glue that held everything together during the time when Tony told them he was seeing a therapist. Paulie was talking behind Tony’s back at the end of the season 1 finale and Christopher was so mad that he ran out of the office. Silvio seemed unsure about it at first but he knew that Tony was the best man that could head the family so he clearly and openly supported him.
