"The Christmas Invasion"

"The Christmas Invasion" was the first episode produced by a production team that knew that the relaunch of Doctor Who had succeeded beyond anyone’s wildest dreams. However, they also had to contend with the fact that the lead role had just been vacated by one of the foremost British actors of our generation. For a whole generation of viewers, this was the equivalent of William Hartnell being replaced by Patrick Troughton. As I said, many moons ago, this required a special sort of story- and again, this is precisely what we got. Russell T Davies takes the bold step of taking the Doctor out of the action for a good portion of the episode. This may, at first glance, seem like madness, but as one watches the episode, the soundness of this thinking is all too evident. At the start, the characters and the viewers want the new Doctor. By the time of the final act, they need him. We are given an invasion crisis that seems hopelessly insoluble without the Doctor. We are even told that the Doctor is ‘broken’- the alien Sycorax cannot be understood, because the Doctor is an integral part of the translation circuits of the TARDIS. The Sycorax invasion itself is shown with a refreshing degree of ‘realism’- without the Doctor holding their hands, the programme shows the government reacting in a plausible way. There are some intriguing concepts, such as ‘blood control’ and the robot ‘pilot fish’ who travel in the wake of another alien force. The Sycorax are a well thought-out alien race, with them treating their science as a form of magic. Davies manages to mix in his trademark witty dialogue with the plot and his skewering of Christmas iconography is funny without seeming ridiculous. In 2009, it is impossible to ignore the fact that this is an antecedent of the outstanding Torchwood: Children of Earth, especially the scene where the A-positives are controlled into standing on the edge of tall buildings and, of course, the sting the story has in its tail- again courtesy of Torchwood. It is testament to the formidable writing on both this and Children of Earth that neither is diminished by the other.

The production is epic, with a giant ship made out of an asteroid floating above London and is expertly helmed by James Hawes. Scenes such as the hypnosis of the A positives are realised excellently, symptomatic of a show that knew that it was a success and resolutely refused to rest on its laurels. Even when it refers to other things (Harriet Jones's television plea to the Doctor recalls Superman II, Torchwood's weapon is like the Death Star) the story manages to make these things its own. Hawes brings a more cinematic feel that is excellently done, making this truly a 'special'. The cast is also superlative. Penelope Wilton effortlessly makes Harriet Jones a credible leader of a major power as well as the slightly batty figure we all know and love and she is ably supported by Daniel Evans and Chu Omambala. Noel Clarke and Camille Coduri again play their parts to perfection- we care about these characters deeply, now, and their inclusion is always welcome.

Now, we come to the Doctor. It is hard to believe nowadays how much trepidation there was over the comparatively unknown David Tennant. However, it was soon clear that we were in good hands. Even in his incapacitated state, Tennant shines and in the utterly glorious revelation of the Doctor in full working order, Tennant grabs our affections and never lets go, from quoting The Lion King to sword-fighting for the planet, Tennant astonishes in every frame he is on screen. However, we must not forget Billie Piper's contribution- it is Rose who must accept this stranger as the Doctor and Piper brilliantly portrays the faith amid confusion that the character must have.

This is a wondrous story that proved that, not only was Doctor Who back, it was here to stay.
