GF trilogy is my all-time favorite. But "Goodfellas" is the best Mob movie. I think of GF Trilogy as a film about a family's evolution, with the Mafia as a defining milieu. But I don't think of it as a "Mob" movie per se. To make an analogy: "Gone With the Wind" is a film about a family's evolution, with the Civil War as a defining milieu. But it isn't a Civil War movie.
