Why anyone would resurrect this sniggering, tired play 30 years after it was written is a mystery. The sole function of Tina Howe's 1976 alleged comedy of manners, which eavesdrops on visitors (and one hapless guard) at a contemporary art exhibit, is to underline her incredible hatred of both human nature and art. This Appetite Theatre production, directed by Michael D. Graham, offers little beyond shrill performances based on stereotypes. Most befuddling is the way Howe has her characters shout, completely missing the fact that most people are intimidated, self-conscious, and largely silent in institutions of high culture. There isn't a whiff of dramatic truth or genuine wit in this show, the worst I've seen this year. Through 3/26: Thu-Sat 8 PM, Sun 3 PM, Chicago Cultural Center, studio theater, 78 E. Washington (enter at 77 E. Randolph), 773-275-1931, $12-$15.
