The Christmas Invasion is a fantastic episode of Doctor Who. It's funny, mysterious, the Sycorax make for great villains, and the ending is phenomenal. Harriet Jones was once again an awesome character; Penelope Wilton is a really great actress. The scene where all of the people are being controlled by the Sycorax and are about to jump was executed very well by the directors- it was really tense and a dark turn for the episode. The spinning Christmas trees and the brass players were also memorable. The Christmas Invasion was a 7/10 for the first 30 or so minutes. The last half of the episode was where it got really, really good. One of my favorite scenes of the episode was when David Tennant came out of the Tardis and challenged the Sycorax to a battle. I liked Christopher Eccleston as the Doctor (he was my introduction to Doctor Who), but Tennant just owns the role and relishes every moment on screen. From the moment he came out of the Tardis to the moment the episode ended I couldn't stop smiling. I love action and fight scenes in Doctor Who (which doesn't do much of them), so it was fantastic to see the Doctor duel with the Sycorax on top of the spaceship. I loved the ending, where the ship leaves and Harriet Jones, the Doctor, Mickey, Jackie and Rose all exchange hugs and boast about the defeat of the aliens. That scene was just so awesome; the characters are all so great, and the scene was a really feel-good ending to the episode. Harriet Jones calling in Torchwood to fire at the ship was a good scene; it was well acted and it develops her character by showing how willing she is to keep the world and Britain safe. Billie Piper and David Tennant have great chemistry as well, and the part when Harriet Jones calls the Tenth Doctor "My Doctor" was really nice.The Christmas Invasion is pretty much everything I like about Doctor Who in 60 minutes: it has awesome action and fight sequences, hilarious moments, well rounded, memorable and recurring characters, great visuals, a feel-good ending, AND it's a fantastic and really fun way to introduce the new Doctor, with the perfect mix of camp and dramatic sequences. The Christmas Invasion isn't a perfect 10/10, but it gets pretty close!

I know many , many people were looking forward to seeing this . The British TV audience had just been treated to a story featuring Christopher Eccleston regenerating into David Tennant at the end of Parting Of The Ways , one of the most beautiful , heart touching scenes the programme has ever or will ever succeeded in doing . Would Russell T Davies be able to keep up the momentum ? Yes is the answer but I shouldqualify this by saying The Christmas Invasion is wonderful in someplaces and rather mediocre in other places Without doubt RTD knows what makes the show work - imagery . If you're my age you'll remember peers discussing the show with phrases like " I remember the one with the giant maggots ...the giant spiders ...the monsters that came out of the sea " In years to come this story will be remembered as " The one where the Christmas tree comes to life and tries to kill Rose , Jackie and Mickey " . This is a great and amusing scene and as Jackie screams " I'm gonna be killed by a Christmas tree " you'll be totally amused . Almost as good is the scene where Rose and Mickey dodge the killer Santas with their ray guns . If you find all this bizarre and far fetched then I'm afraid you just don't understand the spell DOCTOR WHO has cast over generations of audiences for decades and I pity you There are problems and like the successes they're down to RTD . Why is it he has to give a ridiculous name for an alien race ? In this case it's the Sycorax who come across as bad pantomime pirates . Another point is the continuity where the Doctor gets his hand sliced off but is able to grow a new one because several hours after a regeneration a time lord can do this which sounds like cheating and I don't believe for a moment RTD envisaged the severed hand as a plot point for season three of the show . Tennant spends most of his debut in bed which in hind sight is something I'd wished he'd do in all of his stories . I certainly didn't take to him as he falls out of the TARDIS bellowing " I dunnit " in his irritating mockney geezer accent but while being better in latter stories he is often quite worse so The Christmas Invasion deserves at least seven out of ten

One of the best Shows on television and One of the best episodes EVER! The new doctor is Witty as he is Hyper active! The Doctor fresh from regeneration is helpless as earth is invaded! But Rose is in the center stage as the aliens invade! She finds her self facing down the alien leader. And has to over come her fears and doubts as the man she come to love has been reborn as a total stranger! This episode more than any other establishes the future of the show!Lots of references in future episodes will come back to this show even up to current 3/13! So do not miss it! Or you will be wondering about the hand! Not to mention how vengeful a Time Lord can be with 7 WORDS!

I love this episode. It's one of my favorites. Here we see David Tennant for the first time as the tenth doctor( excluding the thirty seconds at the end of the parting of the ways). And he is brilliant. He is totally natural. The rest of the cast are very good as well. Billie Piper is also very natural as the doctor companion. The script is good, with some brilliant lines (see quotes page). The pass of the episode is good, with a good lot of action ( the crash landing tardis, the attack of the father Christmases and the Christmas tree, the sword fight..) but not too much, and there is no excessive violence. In fact there is practically no violence, in less you include the sword fight, and even there everything is kept proper: no blood. We also hear what I think are is the first reference to Torchwood. The episode keeps up until the very end To sum it up, i say go and watch this episode as soon as you can.
