I'm liking this Doctor more and more. He seems somewhat unsure of himself this episode, and I don't love that, but meeting your future might do that to you.

Amy is growing on me more and more. She is rather competent for a companion, and even managed to solve her own problem! Very happy with her.

River... eh. I did want to see more of her, but I could do with or without her at this point. The last thing Smith needs this early is a character to make the Doctor wonky.
