The Irishman is about nothing.
This is not to be taken in the classic Seinfeld-ian connotation of the phrase. The Irishman is certainly about many weighty themes and ideas. It’s about the United States government and the US electorate and capitalism and the means of production and familial relationships and fraternity and loyalty and aging and mortality. It’s even about the proper way to store and transport fish and poultry. It’s about men and their lives and what those lives are, if they are not careful, filled up with: nothing.
