This episode begins with the Doctor and Donna Noble (last seen in The Runaway Bride) investigating Adipose Industries - a very successful fat-loss company. At first, it appears they're together, but we soon realise neither is aware the other is there.
It seems much later than last year, but it's actually a year to the day since the last Christmas special. We quickly find out that the TARDIS hasn't crashed into The Titanic as implied, but rather a spaceship of the same name orbiting the Earth. The Doctor and Astrid1 Peth (played by Kylie Minogue) then battle the corrupt owner of the spaceship and the murderous, robotic host to save the Earth from annihilation.
Set a year after The Sound of Drums, this is a ripping final episode with the Doctor's year long plan eventually playing out to defeat the Master. The Master is shot and refuses to regenerate to spite the Doctor. The Paradox Machine is destroyed and the last year is undone. We discover the true identities of the Toclafane and (in a big surprise) the Face of Boe. At the very end, Martha decides not to travel with the Doctor any longer. So he is now truly the last of the Time Lords and alone again.
A fair episode that covers a lot of ground. The Doctor, Martha and Jack escape back to Earth after the Doctor fixes Jack's Time Vortex Manipulator. They find that the newly elected Prime Minister Harold Saxon and the Master are one and the same. The figure out how the Master is controlling everyone and follow him to the Valiant where they find the TARDIS. But the Master is triumphant. His paradox machine tears open space and time. Six billion Toclafane invade the Earth. The Master kills Jack and ages the Doctor 100 years. Martha escapes.
An absolute cracker of an episode that sees the return of two characters: Captain Jack Harkness and The Master. This is the first part of a trilogy to end Series III and it is brilliant. So much good stuff: why the Doctor never returned for Jack; tie-ins with Torchwood; the end of the Universe; the meaning of the Face of Boe's final words; and the return of the Doctor's nemesis.
A clever, innovative story that involves a young woman following clues left for her by the Doctor in the past, in order to rescue the Doctor and Martha, who have been trapped in 1969 by Weeping Angels. Well paced, good characters and plenty of tension - a fine episode, even though the Doctor, and especially Martha, hardly feature.
This was a drawn out and occasionally boring episode. The resolution of the threat is almost incidental to John Smith, who gradually realises who he really is but wants to remain human. The Doctor, it seems, longs for an ordinary life.
The Doctor and Martha are on the run from the Family and are hiding in England in 1913. The Doctor has taken the extreme step of becoming human to avoid detection. As part of transformation he "forgets" who he is and takes on the persona of a school teacher named John Smith. But the Family track him down. Unaware of who he really is, and with Martha unable to change him back, the Family try to scare him into reverting into a Time Lord by threatening to kill his friend or his lover. His choice. And the episode ends.
The Doctor and Martha materialise on a spaceship in trouble. It's orbiting a sun, unable to escape its pull and there's 42 minutes left until it crashes. The Doctor and Martha save the day in a thrilling story, involving a living sun, with just seconds to spare.
The Doctor drops Martha off at home, her stay in the TARDIS apparently over. He leaves, but promptly returns, wondering what some guy on the TV meant by changing what it means to be human. Martha and the Doctor attend a party, along with most of Martha's family. The host is the guy who turns out to be Professor Richard Lazarus and uses a machine to turn back the clock. He steps out of it looking 40 years younger.
