A memory of Roger Ebert, plus, the circus comes to town by Dueling Critics published on 2013-04-05T16:28:02Z Jonathan pays tribute to his long-time friend Roger Ebert, the godfather of argumentative critics everywhere. Ebert died Thursday at the age of 70. Then Jonathan and Kelly manage to disagree about absolutely everything while agreeing that the musical “Barnum” is an exuberantly presented piece of content-free fluff. Gene Weygandt bedazzles as the circus showman, with an able supporting cast of tumblers, unicyclists and clowns. “Barnum,” directed by L. Walter Stearns, runs through June 16 at the Mercury Theater on Southport Avenue in Chicago’s Lakeview neighborhood. Photo: Roger Ebert (AP) Genre theater review
