In Shotgun Stories, a mother comes to her son’s doorstep at night to tell him that his father is dead. Pause. Crickets. Son responds, stone-faced, “When’s the funeral?” Pause. Crickets. Mom: “You look in the paper.” Pause. “You goin’?” “No.” Shotgun Stories goes on like that for a mesmerizing 90 minutes. Glorious Southern fried sloth, in epic widescreen.
