Billie Piper. A fascinating and very clever story that works on many levels. On one level it’s a character study of Donna Noble and - in some ways - we learn more about her in this hour than we did all season. It’s also an insight into the ordinary world that surrounds The Doctor. In the latter half we get to see a world gone wrong, as it were, but in the first half we see how the ‘normal’ people view these outrageous events from a distance. Events that we see up close every week. Finally, by using Rose the script drops hints about a bigger story that seems to be unfolding behind the scenes. A story that, one would assume, is about to come to fruition. 10/10
