Using the theme of lunacy to unify diverse true-life Latina stories, Teatro Luna comes up with a show that's bold, often funny, and ambitious. Among the highlights: a woman's cartoonish "vigilante fantastica" escapades, a self-proclaimed peaceful person's hilariously foulmouthed road rage, and song-and-dance scenes that pull together ensemble members' confessional stories about sexual obsessions and other crazy stressors. But if you don't know Spanish you'll feel left out at times, particularly in the moon-goddess mythology-lesson transitions. A bigger problem is the way director Tanya Saracho has crammed all the serious stories about abuse and rape into the final 20 minutes. This whiplash-inducing change in tone undermines the humor and honesty of the first 70 minutes. --Jenn Goddu a Through 7/15: Thu 7:30 PM, Fri-Sat 8 PM, Sun 3 PM, Chicago Dramatists, 1105 W.
