Michael Shannon unbelievable.
Closing scene you'd swear it was him.

Little annoying how he's portrayed as a pseudo 'victim' ie you almost sympathise with the character a little. RL he beat the fuck out of his wife, his kids, killed christ knows how many innocent people, some for kicks/boredom etc. Tortured animals.

He was hardly a good family man who just did pro hits on bad guys.

And the 'died in mysterious circumstances pre testifying against the Gambino family underboss' is possible the most gross exxaggeration of literay license Ive ever scene.

The feds had as much interest in laying charges as the Gambino family had on aveging/protecting the most hated rat in LCN history. They'd have loved to see Sammy locked up.
