The episode in its own right is problematic in part, paradoxically, through the things it does right. The parallel universe it creates is gorgeously realised with all the time periods crashing into each other and lots of lovely little touches (I liked not only the fact that Dickens was being interviewed on BBC Breakfast, but that they asked him about his upcoming "Christmas Special.") It's a completely insane bit of setup that, for me at least, made complete internal sense, which is a bit of a feat in itself. (It's hard to describe, but the storytelling was so mental I felt like I should be confused but wasn't.) Throw in the nonlinear storytelling that comes with fighting the Silence and Moffat was really setting himself a technical challenge that he lived up to. The problem is that so much of this is completely irrelevant. The messed-up universe is a result of River Song interfering with a fixed point in time and screwing everything up, so the whole story is building up to the Doctor reasserting the reality where he dies, and then in the final five minutes we find out how he got out of it himself. It's all a bit "dirty birdie" for me: I was expecting a finale that spent 45 minutes dealing with the series-long dilemma; I got 40 minutes of smoke and mirrors followed by a quick substitution. At least the smoke and mirrors is hugely entertaining (that train going into the pyramid!) the first time, but on a second viewing, knowing how little it will all mean, it's hard to care about.
So a bit of a mess, but an entertaining one, and well-acted as ever. I know she's not universally popular (
Once again the finale deals with the main thread of the series while leaving another dangling, which is fine but I hope doesn't happen every year; one thing RTD never learned from Buffy was that a show can benefit from having a different sort of finale every year, and while The Moff has moved away from RTD's particular brand of "bigger is better" at the moment he's in danger of just replacing it with his own repeated meme. Of course with the 2012/13 series' upcoming anniversary celebrations, this kind of semi-cliffhanger is appropriate, and "the fall of the Eleventh" certainly hints at a regeneration. Which would mean Matt Smith bowing out after the "traditional" three years in the role, and would be an appropriate story for the show's 50th. The only alternative that seems suitable would be a multi-Doctor story like they did for earlier anniversaries - I can't imagine David Tennant would take much persuading, and with the change in production team maybe even Eccleston isn't completely out of the question. Of the "classic" Doctors, age would be an issue but we never saw McGann regenerate so he can be as old as he likes if he returns, and Sylvester McCoy always looked about 70 so nobody would probably notice. As for the "Doctor Who?" question that'll prove important in the next series, my only real gripe is the "hiding in plain sight" reference to it: As it's the title of the series it feels as if that's what they're referring to, as if the Doctor knows the title of the show he stars in, which is a bit meta for my liking - this is Doctor Who, not Supernatural.
Shorter-term, I'm interested in what turned out to be the purpose of the series' leadup to the Doctor's "death," namely the idea that the Doctor will now try to operate more under the radar. I have mentioned before that since the relaunch he's become less "madman in a box" and more "greatest legend in the universe" but I'm interested to see how they actually put this into action. After all, the change may have happened circa Tennant's era but it wasn't really anything to do with his performance, the Doctor's always strutted around as if he owned the place. It's everyone else's reactions that have started to change since Ten's day, with all species, not just the Daleks, treating him like The Oncoming Storm. No title given away for the Christmas Special, which is a shame (I assume they haven't settled on one yet, I can't see any reason to deliberately hold the title back from the caption where they traditionally first announce it.) But despite a disappointing Series 6 I'm still looking forward to ithe Special and to Series 7, whenever and it whatever form it may actually turn up.
¹well, that's debatable, but you know what I mean
