I don't like the "cliff-hanger" season finale that everything has now. The Doctor Who episodes of old were each stand-alone episodes, and you could watch them in pretty much any order and not lose anything.
That said, I like how he sees the consequences of his actions. "I caused this world".
Yep. You did. Oops.
I pledge allegiance to the Earth, one planet, many gods, and to the universe in which she spins.
