I wasn't too big of a fan of this episode. It felt rather, cobbled together to me. It seemed like it wanted to be two things, an episode where the relationship between Amy and her fiancee is developed, and a fun old fashioned Dr. Who romp. But it failed at both. I came to the odd conclusion that while both characters, Amy and Fiancee are good, I don't give to craps about their relationship. Add that with the very odd Doctor going to climb a building and hit a switch moment, which felt rather forced to me. Nothing brilliant, or cool, just hey, let me go hit this off button.
Next episode looks great though. Good old brainy thriller.
