In Lynn Nottage's latest play Undine, a black woman who hauled herself from Brooklyn poverty to the Manhattan bourgeoise, suffers Dickensian reversals of fortune. Next Theatre's production, directed by Jason Loewith, exposes the plot holes in Nottage's satire and forces the farce with overly broad acting--as Undine, Jacqueline Williams tones down the histrionics only when she has someone subtly funny to play against, like Dale Rivera as her charming louse of a husband. Yet the production also reveals the playwright's earnest heart and feeling for character, giving us insight into different culture clashes as well as several sharply funny lines. Through 5/7: Thu 7:30 PM, Fri-Sat 8 PM, Sun 2 PM, Sat 4/15, 2 and 8 PM, no show Sun 4/16, Next Theatre Company, Noyes Cultural Arts Center, 927 Noyes, Evanston, 847-475-1875, ext. 2, $25-$35.
