If more local theater companies put on shows as exuberant and sexy as Big Love, they wouldn't have to spend so much time whining that nobody cares about theater. Very loosely based on Aeschylus's The Supplicant Women, Big Love features the squashing of tomatoes, the baring of naked flesh, and a final, orgiastic spree of sex and violence that leaves the stage in shambles and the audience in horny, happy awe. (Balagan Theatre, 1117 E Pike St, 718-3245. 8 pm, $12–$15.)
