An amusing and romantic Christmas special that re-unites the Doctor with River Song in a final farewell.

A solid episode with many strengths to end the series. The hybrid story arc is wrapped up (well, mostly), however, the resolution with Clara was a bit of a let down.

An extraordinary, if occasionally slow-paced, episode with a very clever premise and a jaw-droppping cliffhanger.

A solid, clever episode that is ultimately dominated by the death of Clara.

The climax to the two-part Zygon story has a memorable scene from the Doctor but did not live up to the first episode.

An episode built on a very interesting premise, but with rather uneven execution.

An excellent episode that builds on the previous one and even looks ahead to the future.

The Doctor and Clara encounter a group of Vikings and manage to save them from the Mire. A solid episode with some intriguing points.

The Doctor journeys back in time to save the future but becomes part of events and unable to leave. Seemingly trapped and doomed to die he engineers an ingenious escape. But where did the idea for his plan come from?

Another spooky episode that continues the apparent Season IX theme of the Doctor's death.
