Enjoyed it, thought it was definitely better than the majority of Series 7B and Time of the Doctor.

The first half wasn't on par with the second half, which was brilliant, from the restaurant scene, through to the breathing scene, the showdown between the Doctor and Smith's cameo but the slower pace at the start gave the whole world and story a chance to breathe, which isn't always the case in Who.

First impressions on Capaldi are that he's gonna be great, though it'll be better to start judging him next week when he's sane for the whole episode.
