Robert O’Hara’s new play, Mankind, opens with a gay couple’s strained pillow talk, as one man, Jason (Bobby Moreno), advises his partner, Mark (Anson Mount), that he is pregnant—by Mark. From that simple start O’Hara spins a broad, futuristic satire of sexuality, feminism, religion, commerce and talk shows. It’s more than the playwright is able to manage smoothly, and much of it feels familiar, but it has its moments before it arrives at its circular ending, one reminiscent of Ben Hecht and Charles MacArthur’s Twentieth Century.
