“Most regional theaters would have hesitated to produce a single one of the works in the current Steppenwolf season (which can now be viewed as a whole). Steppenwolf willingly took seven doses of box office poison in the name of its art. Back to back. Especially because it took an inevitable and fiscally sobering toll on subscription levels, it’s an accomplishment worthy of note and admiration. But the anniversary season also reveals something about how much this theater has changed under artistic director Martha Lavey.”
