An atmospheric episode told partly in flashback with a complex story and a new villain.

The Doctor, Bill and (for a change) Nardole, respond to a distress signal and arrive at a space station where oxygen is at a premium and is apparently being overrun by zombies.

Bill and her flatmates struggle without luck to find a new place to live, until a mysterious landlord makes them an offer to good to refuse. The Doctor finds something in their new house to worry him and won't leave despite Bill's best efforts.

A return to form as the Doctor and Bill battle a monster beneath the frozen Thames in early 19th century London, only to find the real monster is above ground.

A quick trip in the TARDIS turns into a bit of a nightmare.

After a whole year off, we finally have a regular episode. It looks like it was worth the wait.

After a year off, the Doctor returns in a witty, whimsical Christmas special.

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.
