Best fictional, realistic mobsters you have seen?

My list: -Johnny Sack. Definitely saw him as on of the most realistic mobsters in the show.

-peter clemenze from Godfather 1. Gotta love the fat loyal, chill capo.

-every single mobster in mafia 2. This game is basically if Michael Scorsese made a video game.

-Ray Boccino from gta iv. Definitely the most realistic mobster in the gta universe. Greedy, but not a monster, smart, got balls. Plus great voice acting.
