While Charlie Rose seems to be a very intelligent interviewer, after watching his show for many years, I come away with the impression that he's quite biased, unless he's in a foreign capital interviewing some tyrant who could easily arrest and jail him if not that he were a famous American talk show host. With guests that he clearly adores, he's overly compliant, and with those whom he quite obviously differs, he's overly scrappy.
Two examples will hopefully illustrate this. When Thomas L. Friedman is the guest (as he has been countless times) , I sit and wait for the moment when Charlie is going to bend forward to kiss Friedman's ring, as if everything Friedman says is as epochal as a papal homily. Contrast that with when someone from the political left is the guest (hardly ever, of course). When Noam Chomsky was the guest several years ago, Charlie attacked from every direction everything that Chomsky said, and that was after Charlie fessed up that Chomsky was one of the most requested guests ever by the viewers.
And lastly, two of my pet peeves. After asking a question of a guest, as soon as the guest begins to answer, Charlie compulsively interrupts with a further refinement of his question. Some guests then just keep talking, leaving Charlie no choice but to button up and listen. The other peeve is how Charlie talks with his left hand, and leaves it frozen in the air in front of the camera after his voice trails off. I want to say to him, "Charlie, put down your hand!"
