Doctor Who's Year (And A Half) Of Hell

The Doctor Who episode "Turn Left" aired last night for the first time in the U.S., and you can read my recap here. I liked it almost as much as last week's episode, in spite of some very puzzling diction from a certain returning character. Oh, and a weird ethnic stereotype. But in general, I liked it a lot. Please consider this a comment thread for people who've just seen the episode to weigh in. What did you think?
