Doctor Who: "The Almost People"

I have two reactions to “The Almost People.” The first: It’s a pretty good follow-up to last week’s “The Rebel Flesh.” I don't know that it solved its predecessor’s pacing problems or developed its themes in any significant way (though the two Doctors proved both fun and poignant) but I liked it. The second: What? Huh? No, seriously. What? Huh?
First things first: After a brief introduction, we get to know the Ganger Doctor who, for the sake of clarity, I’ll just refer to as John Smith. Smith is the Doctor right down to, but not including, his shoes. Or at least we’re supposed to accept that as The Doctor himself has. Which makes sense. The Doctor has a big-tent view of what constitutes intelligent life and, though not human, his sense of humanity extends much further than those who created and used the Gangers as their slaves. It only makes sense that, far from being threatened by Smith, he embraces him.
Others aren’t so quick to do the same. I kind of saw the Doctor/Smith swithcheroo coming and I guess you did too. I think only Amy was reluctant to see Smith and the Doctor as one of the same. That also makes sense. She’s not jealous that Rory is spending time with Jennifer. She’s upset that he’s putting his life, and their life together, on the line for a creature she considers sub-human. (Little does she know how close to home that issue is, but we’ll get to that in a bit.) The Doctor forces her to think otherwise. Which is part of what The Doctor does. If his companions share a journey, it’s a journey toward making them think less like narrowminded, earthbound humans and more like the Doctor. Here Amy takes another step on that journey. (Or does she? Will she remember this? Again, more in a bit.)
So, apart from the last-minute twist, how was this episode? I’d put it about on par with the last. So much of the running around seems like it was there to fill time and the action and suspense weren’t nearly as compelling as the issues around them. (Same as last week, really.) But, like I said, the two Doctors were a lot of fun, and I enjoyed seeing Matt Smith send up his own performance a bit when he played John Smith. It also created some memorably horrific imagery, with the pile of discarded flesh and Jennifer’s monstrous transformation.
