Chewbecca, I think you are spot on there.
Even the earlier series tended to sugarcoat some of the more horrifying stories, but at least the stories themselves were real, and you did have a sense of how brutal life was for many people. But I'm quite fed up of the way that "issues" such as homosexuality are being shoehorned in so that we can see how even in 1960 our middle-class characters had impeccable PC attitudes, which they almost certainly wouldn't have done.
