The theme is that Vito is the number 1 Don, and others try to stop him (Capone, Maranzano, irish, etc.) But he overcomes all obstacles. He has friends all over, and his influence stretches to Sicily. Vito, Luca, Sonny, Capone, and Roth are main characters. Other people are there now, to be there later you know what i mean? You know, Altobello helped kill Ciccio, so hes Connie godfather. People mess with Vito, Luca takes care of them. etc. The Capone Fmaily is important, they NEVER quit until they're ALL dead.
