A hot summer night brings five residents of 218 West 10th to the rooftop. A sixth figure - aka. the Symbol in the Hooded Sweatshirt - hovers over the scene on a water tower. In Terrence McNally's 90-minute talkfest, there is no privacy, yet the five reconfigure into smaller groups, open up, confess, and (though some could wish others grave harm) forgive with the compassion of saints. Even the hooded figure, sought by searchlights and helicopters that blast like machine guns, becomes benevolent. The quintet, it turns out, are not only interconnected, they're wonderful human beings who just need to hear some Our Town Lite pseudo-wisdom about life and loving the one you're with. Best of show at La Jolla Playhouse: Santo Loquasto's set - rooftop, water tower, and Village-eye view of Manhattan. The cast boasts headliners Doris Roberts, Richard Thomas, and Tony Award-winner Harriet Harris. All coax what they can from their roles, though the exchanges and revelations often feel contrived, as if the characters were colored shards, having to conform to a mosaic, rather than people.
