Pacino. De Niro. Pesci. Keitel. Scorsese. It's got to be the greatest mob movie ever? No. It's Carry On Godfather. As a comedy it works but as a drama , given the laughably bad de - ageing effects, it's an absolute disaster. John Travolta's John Gotti comes to mind. It's that bad. But still worth a watch. Goodfellas it ain't.
