I loved this then and I love it now.

This is one of RTD's best episodes and one of the best Christmas specials (it's definitely in the running for my vote).

David Tennant is great, even though he's unconscious for a sizeable chunk. Billie Piper is on top form, as are Camille Coduri and Noel Clarke. Penelope Wilton is simply wonderful as Harriet Jones and the script sparkles around these characters. Tennant's arrival aboard the Sycorax ship thrills and there are few better lines than the Lion King gag.

The Sycorax are a great monster and I love the idea of blood control. I have a bit of a fascination with 'mass panic' concepts (I love a good disaster movie - so you can imagine I'm a bit of a fan of Voyage of the Damned as well) and the scenes of people walking to the top of buildings whislt their loved ones impotently try to stop them is heartwrenching. The mother trying to stop her two children makes my stomach lurch in horror now I have two kids of my own.

The scenes of the Sycorax ship arriving owe more than a little to Independence Day (another favourite film of mine) and I love the fact Big Ben has scaffolding around it as a result of Aliens in London.

I remember on first watch finding the scenes of the Doctor bringing Harriet Jones down a little harsh and unnecessary. Watching it now, many years later after seeing a far darker 10th Doctor, as well as the War Doctor and the very grumpy 12th Doctor, it doesn't seem as out of character as it did back then (even after the tough 9th Doctor). His disappointment in human failure is totally in character, it's just rarely as on the surface as here (at least until Series 8/9). On the flipside, I think Harriet gives a powerful justification of her decision, particularly with her comment about how two men died whilst the Doctor was asleep.

It's very weird to have Torchwood referred to as now, in retrospect, we can imagine Jack pressing the button (I assume he's in charge by this point, I can't remember the timeline - at the very least Susie Costello must be in that bunker - or maybe it's Yvonne Hartmann. Actually, yes, it's probably her bearing in mind what happens at the end of Series 2). Back then, we didn't know what Torchwood was - it was just a word. How amazing to see what developed from that one anagram...

There's a lots of good Christmas stuff in this, particularly the spinning Christmas Tree - totally Doctor Who and totally RTD. The Robot Santas maybe a bit underdeveloped (never quite understood the whole Pilot Fish thing) but they give a good set piece blowing up a Christmas market. I always found it a bit odd, though, that they return - sort of - in the next Christmas episode. I also like the Doctor joining the Tylers for Christmas - which harks nicely back to the 1st Doctor celebrating with Steven and Sara.

A definite favourite of mine.

Banger Christmas special and a really good way to do post regeneration for new viewers I feel

I think The Christmas Invasion is a pretty clever introduction for the Tenth Doctor on RTD’s part. By holding him in reserve for most of the episode we’re confronted with a world where the Doctor isn’t there to save the day - something Russell would return to with even more devastating effect in Series 4.

It’s nice seeing Rose manage things on her own and show off what she’s learned, even though it’s not enough to take the Sycorax down at the end of the day. Her acting as solo lead for most of the episode lets us catch up on her relationships with Jacky and Mickey a bit further, and shows Billie Piper’s chops as a leading actress.

Harriet Jones’ heel turn is a major sticking point for many viewers of this episode, and I agree that the way this pulls such a 180 from what we learn of her in Aliens of London/World War Three is a bit rough. Still, though I think I would have preferred at least one more Harriet appearance in between that two-parter and this episode to give us some more time to build it up, I do think it’s realistic. Showing the fallibility of our leaders is right in line with RTD’s skepticism toward the political class that we see in so many of his other episodes, and for what it’s worth, it is emotionally affecting in this case.

We could argue if the Doctor is right or not to do what he does in destroying her career, but it doesn’t feel to me as if the text is asking us to side with him on this. Coming as it does right after his “No second chances” moment with the Sycorax leader, we see that this new Doctor can be just as ruthless with his favorite species as he is with the aliens of the week. I believe this is the start of the arc that we see conclude in Waters of Mars and The End of Time, where this Doctor grapples with his tendency to play god with history.

Finally, as a Christmas episode, this story captures the vibes of the season and makes for great holiday viewing, even aside from the episode’s individual merits. I rate it quite highly.

👍🏼(7.8) = GOOD!

Thworping through time and space, one adventure at a time!

This is the story that started the annual tradition of the Doctor Who Christmas special with RTD. It is also, incidentally, the first episode for the new Doctor, David Tennant.

The story combines a traditional British Christmas feel with familiar faces (Rose, Jackie, Mickey, and Harriet "We know who she is" Jones) trying to cope with an alien invasion while figuring out who or what the man calling himself the Doctor is, all while the man himself spends a bulk of the story unconscious (this feels like a callback to Spearhead from Space, 1970).

This approach to introducing a new Doctor by landing him in a familiar setting surrounded by different people helps us accept the change and realise that we are still watching the same show. Simultaneously, this modern interpretation of Doctor Who emphasises the companions and their worldview.

The main plot itself is a rather simple alien invasion plot, but it turns pretty fun towards the end once the Doctor gets going properly. The twist that the Sycorax use blood to control Earth's population is pretty good. The entire sequence, from the Doctor waking up, blabbering around, and quoting The Lion King, to him fencing with the Sycorax leader, losing his hand, and then winning the battle with a satsuma, is a captivating and engaging experience. For me, this entire sequence marks Tennant's transformation into the Doctor.

Billie Piper, Camille Coduri, and Noel Clarke are all on fire here, with Piper leading the fray very well and Coduri doing the comedy bit. Mickey proves to be very resourceful here, which seems appropriate for the character. David Tennant is very comfortable in the lead role already, but he's also a bit all over the place so far, though that’s probably the point.

This is also the episode that reintroduces Harriet Jones from Aliens of London/World War Three (2005) as a running gag. Okay, then, Russell! But at least she shows some of her determination and prowess. UNIT is also back in full force, and we get the first mention of the Series 2 arc, the mysterious Torchwood organisation.

To this day, The Christmas Invasion manages to make Christmas creepy. Killer Santas and spinning Christmas Trees of Death make sure of that! At the same time, there's enough of a comedic tone here to not make things too gruesome.

Murray Gold contributes an epic score, but the visual elements are simplistic; the big visual effects haven't aged well; the fencing scene appears a bit clumsy; and the costumes still look fantastic.

The final few moments, with Harriet Jones deciding to shoot down the Sycorax ship, are a New Who equivalent of a similar conclusion in The Silurians, showing the vile sides of humanity that the Doctor frequently loathes. This scene also shows that the new Doctor can have some of Nine's darker sides left.

RANDOM OBSERVATIONS:

• It seems tea is everything the Doctor needs to get a jump start! What a British way of putting it!
• I love the moment where the Sycorax leader begins speaking English in mid-sentence, followed by the Doctor entering the scene.
• They already dropped the "Yes, I know who you are" gag three times in this episode, and it's already old.
• The Doctor's fencing is always such a cool scene, but the one seen here pales in comparison to the one between Three and the Master in The Sea Devils.
• The line, "This new hand is a fightin' hand," is very cringeworthy.
• The end of this episode establishes the RTD-era running gag, which is that the snow falling is always something else than snow.

The memories I have of watching this

I was sitting next to the christmas tree at my aunts house and as soon  as the tree started moving I got up and left where I was sitting
