Yeah, they get very keen and big-brother about it - some of the adverts are deeply offensive.
It is one of those things that would never get invented now but is left because it's there. It's what pays for the BBC so its not going anytime soon as they scream if the subject is raised.
I just finished the boxed set of Cadfael which I recommend to all BR fans and in particular priest/law regents. I'm currently watching the last episodes of Sword of Truth, V, and Stargate Universe. I have been pleasantly surprised by sword of truth, really am not sure about V and fear it is going too BSG, and am happy with SGU although it doesn't match its predecessors in the action department.
