Coordinated by Jean-François Richet, “Blood Father” depends on a novel of the same title by Peter Craig, who offers script credit with Andrea Berloff. The motion picture is essentially one of those salvage missions in which two individuals wind up sparing each other, for this situation John and his long-missing girl, Lydia (Erin Moriarty). She returns throughout his life in the wake of having made a splashy, bloody passage with some vigorously outfitted gangbangers and a volatile number in a suit, Jonah (Diego Luna). Things go south, as they should, and she high-tails it back to Dad.
It’s a strained get-together John is calm, she grunts powder if spotted with comic drama. Their giggles take a timeout when the gangbangers appear, weapons blasting.
