OK, do we have a token black actor who may or may not kiss a white woman? Do we have a black lesbian in a mixed race relationship who gives a BJ to a white bloke? Do we have a white heterosexual woman who falls for the black lesbian? Do we have a token asian as a doctor? OK ... we have now passed all the requirements for a UK "PC acceptable" drama. That said, if you can get over the feeling everything is a "numbers" game, Gough and Watson knock it out the park on this one. SUPERB drama.
