Christopher Durang’s 1999 absurdist drama begins as a dark sitcom: good-hearted Betty finds herself sharing a summer cottage with four funny, annoying, and/or scary roommates. But in the second act it turns into a scathing satire of tabloid TV and sensation-seeking audiences. In this Infamous Commonwealth Theatre production, directed by Joanie Schultz, the ensemble underplays the comedy in the first act, aiming for the reality behind Durang’s characters–a choice that leads to a rich, satisfying ending. Though some of the performances are on the bland side, notably Erica Peregrine’s as Betty, Jennifer Mathews as a delusional matriarch is totally at home in Durang’s world, both hilarious and crazy to the core. Through 10/1: Thu-Sat 8 PM, Sun 3 PM, Live Bait Theater, 3914 N. Clark, 312-458-9780, $8-$15.
