In an excerpt from Josh Schollmeyer's oral history in The Chicagoan, Rick Kogan explores the rival movie critics' complex relationship:
They were like a couple of fucking cartoon characters. If you drew them, you couldn’t quite do the real thing justice—especially in the early days with those 1970s clothes. They didn’t look alike, they didn’t sound alike, and they didn’t think alike. They both had a much different delivery—Roger more contemplative and Gene kind of pushy. Plus, Gene was so much more palpably opinionated than Roger. Roger seemed to offer an opinion; Gene jammed his opinion down your throat.This 2010 Esquire profile of Ebert is worth reading, incase you're interested.
