I enjoyed tonight but when they split up (when the alarms went off at first) I couldn't help but feel the Doctor was too calm! The doctor I've grown to know and love would have been more "Oh, okay.. I'm guessing that's not in the architect's plan.... um uh you two go that way we will go this way" with a bit more 'flapping' and mind cogs... That said i did like it.
I also instantly felt sorry for The Teller, i was wondering why such a powerful creature would let anyone chain it up as a prisoner So the end was just perfect for me!
Loving the Clara character enhancement through out the new series but it is ringing alarm bells for me that it's a build up before a massive blow.... I cant help thinking they are going to kill her off in an epic way
