Well, Whovians, he’s back — and he spends most of his own debut fast asleep in a pair of borrowed pyjamas. After the tears and time-vortex fireworks of The Parting of the Ways, I sat down to “The Christmas Invasion” absolutely desperate to meet this new Doctor properly. And Russell T Davies, the cheeky so-and-so, made me wait almost the entire hour for the privilege. It’s a bold, borderline reckless way to launch a brand-new leading man — bench your hero for two-thirds of his first outing — and by the time the credits rolled I was completely, hopelessly sold on David Tennant’s Tenth Doctor. Let me tell you why.
A Doctor Fast Asleep
The TARDIS comes screaming down out of the sky and clatters into the Powell Estate, and out spills a stranger. That’s the whole gamble of this episode right there. We know he’s the Doctor — we watched him regenerate — but Rose doesn’t feel it. This isn’t the man who took her hand and told her to run all the way back in Rose. The leather jacket, the northern vowels, the haunted eyes are all gone, replaced by a gangly, grinning face she’s never seen, who promptly babbles a few cheerful nonsense words and collapses. Billie Piper is quietly heartbreaking here. Rose spent an entire season learning to trust one face, and now she’s sitting at a bedside willing a stranger to wake up, terrified that she’s lost her Doctor for good.
While the hero snores, Davies does what Davies does best: he turns Christmas itself into a horror show. A brass band of robotic Santas — pilot fish, scavengers drawn to the crackling regeneration energy still leaking out of the Doctor — open fire in a crowded shopping street. Then the Tylers’ festive spirit turns homicidal when the Christmas tree whirrs to life, spinning like a buzzsaw and chewing its way across the living room. It’s daft and delightful in equal measure, and it’s a very deliberate stall: the Doctor briefly stirs to zap the tree with the sonic screwdriver, mutters an ominous question about who’s controlling all this, and drops straight back into his coma. The message is clear. Earth is in real trouble, and this time the man who usually saves it is unavailable.
Blood, Snow, and the Sycorax
The wider threat is genuinely nasty. The British space probe Guinevere One, meant for Mars, gets swallowed instead by a jagged asteroid ship crewed by the Sycorax — bone-masked, blood-drinking warriors with a real Old Testament swagger. Using a sample of human blood pulled from the probe, they trigger “blood control,” and suddenly a third of the planet — everyone with A-positive blood — sleepwalks to the nearest rooftop, ledge, and multi-storey car park, standing motionless at the edge, ready to step off on command. It is one of the eeriest images the revived show has produced: whole crowds swaying on the skyline of London, a mass execution held in reserve as a bargaining chip.
And who’s left to answer for the human race? Prime Minister Harriet Jones. Yes, that Harriet Jones — the plucky backbench MP from Flydale North who survived the Slitheen’s Downing Street takeover in World War Three, the one the Ninth Doctor cheerfully tipped for greatness and three glorious terms in office. Now she’s in Number Ten, and Penelope Wilton plays her as the beating human heart of the whole episode: decent, frightened, and doing her level best to hold a terrified country together with the Doctor nowhere to be found. The running gag survives her promotion, too — she still flashes her ID and announces “Harriet Jones, Prime Minister,” and she still gets the weary “Yes, I know who you are” from everyone she meets, up to and including an alien warlord. It lands every single time.
When the Sycorax teleport Harriet, project scientist Daniel Llewellyn, and UNIT’s Major Blake up to the ship, Rose, Mickey, and Jackie do the only sensible thing and drag the unconscious Doctor into the TARDIS for safety — only for the ship’s tractor beam to haul the whole blue box aboard the asteroid anyway. What follows is one of Rose’s bravest, most quietly devastating moments. She steps out, squares her shoulders, and tries to face down the Sycorax with the Doctor’s own borrowed authority, invoking every bit of alien law and swagger she’s watched him use all year. And the Sycorax simply laugh at her. It doesn’t work, because she isn’t him, and you can see the exact moment she realises it. The bluff collapses. Earth is out of options.
The Tea, the Sword, and the New Doctor
And then — a cup of tea. A little spilled tea, seeping into the TARDIS console and feeding a last jolt of energy back into her sleeping pilot. The doors open, the Doctor strolls out in his dressing gown, and with a grin he asks the only question that matters: “Did you miss me?” Reader, I cheered.
What follows is the most efficient character introduction Doctor Who has ever done. In about five minutes flat, Tennant’s Doctor establishes exactly who this new man is. He exposes the blood control for the empty threat it always was — a psychic con job that could never really make anyone jump — and releases the sleepwalkers with a flick. He rifles through his own personality out loud, delighted and alarmed to be discovering it in real time. And when the Sycorax leader refuses to leave, the Doctor invokes the ancient rules of combat and challenges him to a sword fight for the fate of the planet, winner takes all, still in his pyjamas.
The duel out on the hull is glorious. He gets his hand lopped clean off — and then, because he’s barely fifteen hours into his regeneration cycle with energy to burn, he simply grows a new one, calling it his “fighting hand” as he comes back swinging. It’s cheeky, it’s a little bit terrifying, and it tells you everything: this Doctor is a showman who will absolutely weaponise the wonder. He wins, spares his opponent’s life, and turns his back — at which point the beaten Sycorax leader hurls himself forward for a treacherous killing blow. The Doctor doesn’t even look. He flicks a satsuma, hits a release, and drops the man to his death, delivering the line that becomes his whole moral thesis: “No second chances. I’m that sort of a man.” Mercy, offered once and exactly once. That’s the Tenth Doctor, fully formed.
Six Words and a Snow of Ash
The Sycorax are beaten and warned to spread the word that Earth is defended. Victory. Except Harriet Jones, safely back on the ground, gives an order — to a secretive organisation called Torchwood that nobody’s ever heard of — and a great green bolt of energy stabs up and blows the fleeing ship out of the sky. It’s a chilling turn, and the Doctor is incandescent. The enemy was leaving. To him this isn’t defence, it’s murder, and the argument that follows crackles with a temper we haven’t seen on this scale before. Harriet insists she has to protect her people from the things that come in the night when the Doctor isn’t there to help. He doesn’t shout her down. He leans in and murmurs six words to her aide — “Don’t you think she looks tired?” — and just like that, plants the rumour that begins to unravel her before the episode is even over. It’s the most unnerving beat in the episode. This warm, funny, pyjama-clad new hero can topple a sitting Prime Minister with a whisper, and the show lets us sit with the question of whether he had the right. (Who Torchwood actually are, and why Britain is quietly building alien-killing weapons behind everyone’s back, is left dangling like a loose thread nobody’s meant to notice yet.)
Then the ash comes down. The debris of the Sycorax ship drifts over London like snow on Christmas morning, and the Doctor tells Rose the loveliest, saddest little truth of the night: “It’s not snow, it’s ash.” The coda is pure warmth — Christmas dinner round the Tylers’ table, paper crowns and crackers, the Doctor finally picking out his brown pinstripe suit and long coat, choosing his new face’s new look. Rose gets her Doctor back. Not the same man — a different one entirely — but hers, and she chooses to keep travelling with him. After an hour of dread, the show hands us hope with both hands.
What The Christmas Invasion Leaves Us With
For an episode that keeps its lead unconscious for two-thirds of its runtime, this one does a staggering amount of heavy lifting. Here’s what it plants:
- A wholly different Doctor. Where the Ninth was coiled and war-haunted, the Tenth arrives manic, romantic, and quick to anger — same man, brand-new weather.
- “No second chances.” The satsuma and the sword lay down this Doctor’s moral line in a single, unforgettable stroke — he’ll show you mercy, but only once.
- Rose’s leap of faith. She learns the hardest companion lesson there is: to love the man and not the face. That’s a bond that just got deeper.
- The cost of the Doctor’s judgement. Bringing down Harriet Jones with a whisper shows a Doctor willing to play god with human affairs — and the episode is honest enough not to tell us he was right.
- Torchwood. A ruthless, secretive British power is out there, arming itself against the stars. File that name away.
- A Christmas Day Doctor Who actually works. Davies bets the nation will make room for an alien invasion between the turkey and the presents, and the gamble pays off completely.
Rating: 4.5/5 — A debut with the nerve to sideline its own hero and still stick the landing. Docked half a point for keeping me waiting, though I’d argue the wait is the whole point.
Whatever this new Doctor is — and he’s clearly still working that out himself — I am completely on board. Pass me a paper crown and pour the tea; I’m ready for wherever that big blue box lands next.
