With each successive scene, Guirgis peels away layers, and we learn more about Walter: He basically drinks from morning to night. There’s more to his shooting story than we thought. And he has a real mean streak toward the end—truly avaricious and petty. Yet we’re rooting for him despite each disturbing discovery. Henderson, an exceptional stage actor who’s perhaps best known for his roles in August Wilson plays, gives a bravura performance—all the more impressive considering he’s seated for most of his scenes. In his dalliance with the Church Lady (Liza Colón-Zayas, another Guirgis vet)—which features the wildest passing of the Communion wafer you’ll ever see—he’s confined to a wheelchair; and he’s hooked up to an IV and bedridden for an uncharacteristically restrained confessional with Junior. Judging by the entrance applause, Common is this production’s biggest draw, and the neophyte stage actor seems to still be finding his footing. But he’s sweet and subtly charming in a rooftop scene with Colón, and powerful in the aforementioned muted emotional exchange with Henderson. Guirgis gives his characters plenty of R-rated barbs and razor-sharp banter, but those smaller, low-key moments reveal Riverside’s bruised, battered heart.
