New Leaf Theatre is billing Lisa Loomer’s odd, intriguing play as a romantic comedy. Girl meets boy, and in a single night they fall in love and into bed, then fall out over issues like marriage, kids, and the importance of art in history. Loomer aims to provoke, but under Brandon Ray’s direction, this production can be plodding. Isabel Quintero offers ethnic stereotypes as the girl’s Mami, but at least she’s energetic: no one else in the cast has her vigor. The two protagonists, portrayed generically by Georgann Charuhas and Michael Derting, fail to make much of an impression. Though entertaining at times, the couple’s lonely search for love evokes little empathy. Through 4/8: Thu-Sat 7:30 PM, Lincoln Park Cultural Center, 2045 N. Lincoln Park West, 773-274-9026, $12-$15, industry nights Thu.
