Albee's title applies to virtually any scenario. But Agnes and Toby are keenly concerned with the delicate balance of keeping reality -- or anything, or anyone, unpleasant -- outside their front door...Agnes is tightly wrapped, in terms of both manner and costume, which smartly underscores the sense of insularity. Close, with her aristocratic take on Agnes, comes within inches of coming off as arch. That approach doesn't hurt the character. But Close's unintentional habit of tripping over Albee's dialogue doesn't help. Lithgow, meantime, is riveting every moment he's on stage -- which is a lot -- even when Tobias is silent. As he takes the character from quiet restraint to explosive urgency, he doesn't miss a beat and never for a second loses his equilibrium. His is a delicate -- and distinctive -- balance.
