Dunno - let us know what you decide to watch

Once Upon a Time in America

The original GodFather was an incredible movie IMO

A Bronx Tale or Goodfellas for me

Im a fan of Carlitos Way

Not sure but in my opinion this falls into the category but i always loved A History of Violence.

The Godfather trilogy is definitely the best ever in my opinion.

I always enjoyed Donnie Brasco. The new Netflix series Fear City is good too

I've just recently finished the series Bad Blood, it's on Netflix. A irish guy rises to be the right hand of a Capo. The Capo rises to be a Don and takes the irish on a pretty good adventure.

The Irishman on Netflix was pretty good. I quite enjoyed the cast lineup too. 

I quite liked The Irishman on Netflix which came out last year. I thought the cast lineup was pretty good too. I'd watch almost anything with De Niro in. 

I thought the same thing about the irishman it just asnt that good, i did not lie them taing cedit fo the hit on hoffa, goodfellas ais best

In my opinion I think the Godfather was the movie that made the mob life famous and attractive.   Then Godfather two and three just added to the story.  Mobsters doesn't get enough credit but the Godfather trilogy was what opened my eyes to investigate and play here.  

La Haine, and Le Prophet - two extraordinarily good films

Any sane person would know that The Godfather (primarily the first one) holds up as the greatest Mafia movie of all time in terms of origin and importance and background. Goodfellas is another good one out there for more casual watchers.

The Irishman is fine, it just contains some falsities within but is otherwise pretty decent.
