Somehow I missed yesterday’s This Week on ABC, which marked the debut of the show’s newest host, Christiane Amanpour. But Tom Shales caught it. And he didn’t much like it. One of the problems, according to Shales, is that “[Amanpour is] miscast for the role, her highly touted global orientation coming across as inappropriate and contrived on a broadcast that for three decades has dealt primarily with domestic politics, policies and culture.” It gets worse.
