No real spoilers here.

Still a bit about the Doctor Who finale though so if you'd rather not take the chance, don't read on.

Just a brief note about a textbook example of how to write well but manage brevity. In a single scene, with entirely convincing dialogue, Steven Moffat managed to establish that we were in a new Universe, describe how the new Universe differed from the old one, explain that there were some people who remembered the old one, briefly give some hints about the social set up in the new UK, show that Amelia's aunt not only considered her to have mental problems but had tried to get them treated AND include a joke about Richard Dawkins.

It's taken almost as many words for me to describe it as he used to do it. If that isn't a model of concise writing, I don't know what is.
