The Godfather was a fictional movie. Donnie Brasco was non fictional unless of course you don't want to believe agent Pistone because he told the truth about the Bonanno Family.
Truth about what? Yeah they got hit pretty bad. They came back to prominence under Joe Massino and then he flipped, and they haven't been the same since.
