About as good as any I've seen. They covered the half century of the band, warts and gems. Lots of great musical cuts. It looks like they interviewed (or tried to interview) everyone associated with the band - performance and management. The five people with the most screen time were the 4 original band members still there, and Danny Seraphine. Peter Cetera was one of the people who declined. CNN was an odd spot for the show, but I think it was extremely well done and enjoyable.
