I'm afraid I disagree. Derek Thompson, who plays Charlie Fairhead, must be one of the most limited actors I've ever seen on TV. He has no range whatsoever, and he only has one expression: mildly constipated. He was predictably wooden last night, and when I see him I always think of Dorothy Parker's description of Katherine Hepburn - 'she runs the gamut of emotions from A to B'.
Not only that, but a while back when details of the salaries of BBC employees was leaked, it emerged that he is one of their highest-paid actors, on a whopping £400,000 a year.
