During Bertolt Brecht's The Threepenny Opera - the German dramatist's revolutionary musical-comedy collaboration with composer Kurt Weill - we're meant to feel uneasy. With its cast of beggars and rogues, obliteration of the fourth wall, and refusal to cater to conventional audience expectation (the songs here, devoid of proper finales, don't so much finish as stop), The Threepenny Opera is a fascinating, deliberately alienating piece. Our enjoyment stems from how unconventional the show is, but in no traditional sense are we meant to simply like it.

So in regard to director Corinne Johnson's Depression-era Threepenny Opera that recently opened St. Ambrose University's 2006-7 theatre season at the Galvin Fine Arts Center (and closed on October 15), was it a failing or a blessing that so many of its performers were so damned likable?
