Doctor Who 6x01 The Impossible Astronaut

Yes, this is a very belated reaction post, because I've only just watched it. With my sister, who had already seen it, but it was fine, she didn't spoil me or anything. And I am writing this before I see the next part, because I want to be free to make my theories without spoilers.

I didn't check who this one was written by, but it wouldn't surprise me if it was The Moff. It has the hallmark timey-wimeyness and the high creepiness level (and River Song). (checks) Yes, it was written by him.
