I just adore this! Tennant and Tate together are gold and watching this made me desperate to rewatch all of Series 4!

There is so much that's great about this episode, but the best bit is the script. The dialogue between Tennant and Tate is perfect and plays as a perfect contrast to the smugness that had crept into Series 2 between the Doctor and Rose.

The rest of the cast quickly define their roles and it is a testament to Tate and Jacqueline King that their performances continue seamlessly over a year later; such a terrible shame that Howard Attfield - who is also very good in this story - was too ill to continue in the role and, ultimately passed away. Don Gilet is great as Donna's fiancee and alien collaborator, Lance.

The TARDIS chasing Donna's taxi down the motorway is another great sequence perfect for a Christmas day episode - lots of action and laughs is precisely what we want on Christmas Day. It makes the rather dark turn the story takes at the end a little awkward, foreshadowing the direction the 10th Doctor will take, although not for a couple of series yet (so it seems a little out of place here).

The other element I can never quite make my mind up about is the Empress of Racnoss herself. Sarah Parish is having a whale of time chewing the scenery (and the lights, script, CGI effects and probably a couple of gaffers and a teaboy while she's at it) but her costume is so immobile that it just makes the finale all a little static. No amount of quick cuts and edits (which are horribly disorientating) can make up for the fact that she is stuck in a spider's arse for the entire time she is on screen. She is far mor effective when just a spindly arm aboard her webstar (a great spaceship design).

The chaos of the webstar's lasers is a bit naff too and nowhere near as scary as the blood-controlled humans of The Christmas Invasion. It's more reminiscent of the slightly impotent Auton massacre from Rose. Much better is the attack by Christmas baubles at Donna's wedding reception.

Oh, and its a bit of a shame it clearly isn't Christmas Eve in any scenes set outdoors during the day, because it's so blooming sunny!!

Yes, I have a few more niggles with this story that The Christmas Invasion, but the core of Tennant and Tate is more than enough to keep me coming back to this episode. Definitely in the running for best Christmas episode.

I love how this story shows sometimes people meet the doctor and can’t accept the offer of travelling and later we follow up on that later I love it

Lovely my Donna!

Amazing they both see each other's truth in their own best and worst time!

Very happy to see a woman so human will be brilliant, not dimmed even in the light of the doctor.

This episode is fun but not fantastic. I get why some people don't like it, and the comedy can be a little lacklustre along with the special effects, but it is a very strong performance piece that introduces us to our first little taste of Ten and Donna. I do think it is a much-needed cool-down episode after all the drama of Doomsday. The light-hearted nature of The Runaway Bride is welcome in that regard, even if I wasn't laughing *that* much along the way.

I also really like the Racnoss as a plot point, showing the more interesting aspects of the Doctor's darkness growing within this character at the time and I am especially here for that. I think that particular angle on the character is our main draw for an otherwise pretty mediocre production otherwise. It's also really neat to introduce Donna here only to have her return later in such a major way (and return she would a few times now, which is cool too!).

As much as I love what is going on with the Doctor and Donna when dealing with the Racnoss, the aliens aren't really the best looking of this era and that holds things back a bit because of it. I also found Sarah Palish a little too over the top, even if that was intentional in her performance. It's fine, but definitely worth watching, even with a good amount of unnecessary choices like the evil Christmas trees returning. For that matter, this really didn't feel like it needed to be a Christmas episode at all. It also gets incredibly overstimulating and overwhelming at times.

Easily the best Tennant Christmas Special. It's for sure one of those episodes which won't be for everyone and Donna and/or the Racnoss are definitely going to get on your nerves at least once here, but I think it's just nice? And cosy?

It just doesn't really take itself too seriously, which I think is a tone that just fits Christmas really well, but also has an underlining level of darkness to it, just to give it that lil extra bite. The Racnoss is also superbly realised and they're given good amounts of backstory to get you quickly invested.
