This episode was a pretty obvious showcase of the new companion and it left a boatload of questions. It was enjoyable and presented a very compelling question of Oswin, but the plot of the crisis neither really mattered nor was it explained how the crisis was averted. It served the purpose of getting the viewers excited about the second half of the season, but as an episode on its own, I wasn't terribly impressed. But bring it, spring 2013.
