The old man has told this fable many times before, but it’s been a while. Delighted to have an audience, he can’t help but take tangents and add embellishments that make the fable as drawn out as a four-day drive from Philadelphia to Detroit. Still, there’s the same cast of characters portraying the survivor’s tale of allegiance versus betrayal, honor versus law, the family business versus the business of family. But with one more deep directorial breath, Martin Scorsese twists the ending. In “The Irishman” (2019), we’re left to wonder whether it would have been better to have lost bravely.
