Deniro plays his only character he's always played, which is tired and worse now that he's so darn old and feeble. Pesci is the same charter as any movie he's done. Pacino as well but he is the most believable via CGI.
Dear Hollywood and Scorsese, the rest of America is tired of these stupid NJ/NY gang movies. Find another genre and leave this one to its death, puh-lease.
