SPOILERS. At the start of season 6, the Doctor died. And, at the very end, he --sorry, hang on.
Alright. He survived. I don't think very many people really believed he wouldn't. (I know at least one person who did, but it seems unreasonable to think that the BBC would let them end the show.)
I blogged recently about Doctor Who and humanism, and I think it would be fair to say that I had faith in Steven Moffat's ability to pull this plot out.
That is, I was confident the Doctor would be fine until a few weeks before the episode, a couple of days after The God Complex.
If you watch the show, and have an obsessively philosophical bent, you may have noticed that the new series has an underlying theme of the dangers of extremist religion. Doctor Who has always been themed around opposition to the fears of the British public, hence the Nazi-like Daleks and communistic Cybermen of the old series.
The God Complex was about the dangers of faith -- a Minotaur-like alien that feeds on faith was manipulating captured individuals into re-framing their individual faiths into faith in the Minotaur.
The context of the episode equivocated faith in Islam, conspiracies, oppression,
and the Doctor.
It occurred to me, just in time to start to worry, that Moffat's plan might have really been to kill the Doctor. To end the series on the lesson that, sometimes, heroes die. Sometimes, they don't come back. And that any idol can be dangerous to put your faith in.
In the end, the way the Doctor got out of it -- the endless repetitions of "The Doctor Lies" and "Time can be rewritten" set up his clever manipulation sufficiently to justify his weaseling out of it. As part of the story of the series, I thought it was pretty good, though it wasn't quite as brilliant as I expected it to be. It worked, but it was more 'acceptable' than 'genius.' And the episodes leading up to it did manage to persuade me that it was possible everything could end. That was impressive.
