Director Arin Arbus skillfully moves her performers around the stage (grungily built by Riccardo Hernandez and adroitly lit by Natasha Katz) and into and out of their convincingly un-stylish clothing (designed by Emily Rebholz), with no attempt to glam up the crummy Hell's Kitchen studio locale. This is the sort of piece where direction ought to be invisible, just clearing space for the actors to breathe and fill the air, and Arbus does fine work. McDonald's Frankie is perhaps more vulnerable and jittery than the script calls for at times but shows inner strength and fire when needed. It's a pleasure to see Shannon luxuriate in a role that plays to his goofy, boyish side. Together, they forge a bond that's deeply moving, a prickly, organic tapestry of comic fluster, flashes of raw hurt, and pulsing erotic heat.
