Glib TV writer Theresa Rebeck makes an agora of a women’s knitting circle, airing all manner of thirtysomething gripes: workplace unfairness, marital disillusionment, the general shortage of acceptable men. Rebeck gives all the actors a juicy rant or two, but again and again she overshoots the mark, more or less forcing them into look-at-me hysterical performances of the most nausea-inducing order. As the tone lurches back and forth between sitcom silliness and Lifetime-channel sobriety, Rebeck’s insistence on female powerlessness in the battle of the sexes grows perplexing: is she deluded or just being disingenuous? Whatever the case, this whiny pre-Sex and the City cultural artifact wastes the efforts of a talented cast. Through 4/30: Fri-Sat 8 PM, Sun 3 PM, Actors Workshop Theatre, 1044 W. Bryn Mawr, 773-728-7529, $20-$25.
