Actors not Italian enough, and bad casting
Compared to films like Goodfellas or Godfather, the actors in this film didn't look or act Italian or Sicilian enough.
John Travolta's portrayal of Gotti was terrible.
And Sammy The Bull Gravano, in real life he was a light featured 'white' looking tough guy. In this film they portrayed him as a dark featured skinny guy. The total opposite of how he actually looked.
This movie doesn't paint an accurate picture of the individuals it features or even the Sicilian/Italian race. Its disinformation.
