^Guess I'm the only person who likes Amy. I'll be sad to see her go. But then, I like Clara/Oswin as well so far.
Anyway, I enjoyed the episode. It was nice to see them do a Western. And I liked that there wasn't a clear cut villain, he was a morally ambiguous character. It was good to see them acknowledging the Doctor's tendencies to push the moral boundaries in recent episodes. I wonder where they're going with this storyline.
