I just finished watching the whole thing. I'm in the US. It was good, well produced. Two things:

'Experts' often refer to some top mob guys as 'people who could be successful in legitimate business'. Michael Franzese is one of those people. Very intelligent and articulate.

The documentary would be good for people who are just starting to learn about the mob. For those who have studied the mob for a while and have a good amount of knowledge pertaining to the mob, this is merely a rehash of what we already know.
