...has left me none the wiser. The satire on reality TV was somewhere between turgid and valid (it's an easy target, but it is also a bloody worthwhile target). The episode kicked into gear as the veneer of humour fell away steadily, leaving dread and paranoia. Even with the resurrection (again) of the Daleks, and the hint of a possible return for Davros in the trailer for next week, we're still guessing at the wider significance of the Bad Wolf motif. But then, Davies is gradually tying even the weaker elements of earlier episodes into his over-riding arc, making you re-evaluate random events that maybe weren't so bloody random at all. Bravo again, you big Welsh poof.
