If you like a slow, carefully developed, beautifully acted, funny and articulate piece of parlor theater, complete with a heart-wrenching scene or three demonstrating alienation between neighbors and genuine intimacy among friends, this is for you. If not, not. With its two deaths or near-deaths, this is more than talk, but still if pure conversation strikes you as self-indulgent or tedious, rather than (in this singular case) genius, why not pass?
