I did enjoy the new episode. You can tell the production values are getting even better with this season. I wonder if they got a boost in their budget because of the new found success they are having in the USA?
It did feel more "self contained" then the older episodes, but we won't be able to get a real feel for this until a few more in. I'm going to be somewhat disappointed if there is no real arc to follow.
Some quick SPOILER filled thoughts.
Warning: Spoiler! (Click to show)
Have to give them props for keeping Jenna-Louise Coleman's appearance in the episode a secret. No one was expecting the new companion to make an appearance so soon. My absolutely jaw dropped when I saw her face.
Did anyone notice her name in this episode was Oswin instead of the rumored name Clara? Could be a hint to how they will reconcile how the Doctor left her in this episode to her eventually joining him full time on the show.
