Dr Who's first mini-series of 2011 comes to an end with a story that no one with any sense ever thought would tie up all its loose ends, and surely everyone knew would create new ones.
Having decided to rescue Amy from the evil eye-patch woman and her lackeys, the Doctor recruits an unlikely army of Silurians, a Sontaran, a blue man and some pirates before setting off to get her back. After a daring raid on the bad guys' asteroid, it seems he's succeeded but, while he frees Amy, in his over-confidence he fails to realise until too late that he's not rescued her baby, leading to the deaths of a number of his accomplices and giving River Song a chance to hand him a Davros-style lecture about his nature before she finally gets round to revealing who she actually is.
That aside, the amount of build-up the Doctor gets in this episode's quite startling and there's no denying that, clearly starting to believe his own publicity, he needs to be taken down a peg or two - although it's hard to see how the writers can possibly turn the Doctor away from seeming like the deadliest being in the universe after all the triumphs against ridiculous odds he's had over the decades and all the ones he'll inevitably have in the future.
Probably the weakest element character-wise is the sight of Rory being bad-ass with the Cybermen. It doesn't matter how hard Arthur Darvill tries, it's still impossible to see him as anything other than amiably inept.
If Russell T Davies got accused of sometimes trying to cram too much into his epics, Steven Moffat takes it to a whole other level as he tries to pack an entire RTD style two-parter into just 45 minutes. Largely he succeeds. Despite so much having to be fitted in, the pacing mostly feels right. At times it all seems a bit too pumped up for Dr Who - especially the Doctor enjoying the Spitfire attack on the base a little too much for comfort - but, in fairness, that issue's addressed with River Song's lecture.
So, the Doctor's succeeded and he's failed. What next? We still don't know who's actually behind the scheme to nab Amy's baby - although there's an obvious set of suspects - and how does Hitler fit into it all? We'll have to wait a couple of months to find out.
But just what was that post-credits shot all about?
