It'd appear that sometimes in life the worst thing you can do is open a door. That's why I have a cat-flap fitted, and why I crawl through it every night to preserve my dignity. But I'm not going to let that stop me as, for one night only, Steve Does Dr Who flings open the doorway of Review and leaps, face first, into the Chamber of Opinion.
Looking for yet another holiday, the Doctor, Rory and Amy find themselves in a hotel with a nasty habit of bumping off its "guests". Once the hotel's made each "guest" enter a room that contains his or her darkest fears, they develop a compulsion to worship a resident Minotaur which then comes to kill them.
It turns out the place isn't a hotel at all but an automated space prison for the Minotaur which feeds on people's faith. And now, minor cast members despatched, Amy's next on the hit-list. Is this the end for our plucky heroine and her rather fetchingly decorated fingernails?
Of course it's not. Just as the Minotaur's about to get her, the Doctor kills it by talking Amy out of her long-standing faith in him, thus robbing the creature of its food source.
Deciding he can't keep putting Amy and Rory in such danger, the Doctor then leaves them behind on Earth, with a new home and car he's somehow acquired for them, then sets off to roam the Universe alone.
At last, after a string of episodes that've almost worked for me but haven't quite got there, The God Complex is an story that really doesn't have anything for me to complain about. I didn't feel any great emotional involvement for most of it but perhaps in the end I didn't need to. It seems that, provided you play it straight, you can't go wrong with the old Agatha Christie, "Let's kill everyone off one at a time while the protagonist tries to work out what's going on," format but it was well structured, paced and performed, and how can you not love a Minotaur - especially one whose horns scrape the ceiling?
I am a little concerned though at how easy it was for the Doctor to dispel Amy's faith in him. Basically all he had to do was tell her to drop it and she did. I mean, Colin Baker once tried to strangle his assistant. That's the sort of thing that really shakes a companion's faith.
But is there some significance in the fact that the evidence of this episode is that Rory appears to have no fears and no faith? Is this just one of those things, or will it prove significant? Could it mean there's something about Rory we've not been told? I still keep going back to the end of The Impossible Astronaut where it seemed The Silence had zapped him, only for him to turn up alive and well at the start of Day of the Moon with no explanation for what'd happened in between.
So it's farewell to Amy and Rory. They haven't always worked as characters but they've had their moments. And shall we ever see their likes again?
Of course we will. Is there really anyone who believes the Ponds won't be back?
