Although it has its amusing moments, in eneral the plot does not convince.

In truth, there is barely enough story here to make a film.

While it doesn't offer any answers, it both thrills and makes you think.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.

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

Fresh from a transformation, the Doctor and Rose return to Earth to spend Christmas with her family. However when trees and Santa's start playing up it is apparent that this is no ordinary Christmas and some sinister force is at work. Still in a weakened state, the Doctor loses consciousness and cannot be revived by Rose. Meanwhile a spaceship positions itself above London and uses some power to control a large section of the population and make them stand on high buildings, ready to jump. The Prime Minister is desperate but seems left with no option but to make a deal with the powerful Sycorax.I watched this special again last week on UK Gold, away from the hype and worry that came with it the first time round. This was the bridge between the "first" "new" series and the second or, more importantly, the bridge between Eccleston being the Doctor and David Tennant taking over the reins. As such there was always going to be an element of making that leap and then also the emphasis on Tennant making the role his own so that the new series could just start with the majority of the fuss over and done with. The first half of the special keeps the Doctor tucked away and builds the plot while also using this as a way of emphasising his entrance when it comes. The story is a good one which does more or less manage to bring in all the elements that the family audience (and big audience at that time of the year) requires. Although it is obviously restricted by the child element of the audience, the tension is built well and the aliens have a genuine threat. The spinning trees etc were all a bit silly but I suppose that does seem to come with the territory now.Of course the big thing in the special was Tennant and I have to say that this didn't win me over to him. As his seasons at the helm continue I have come to like him more but I suspect that has an element of me accepting him rather than him being brilliant. Here I felt he was too over-the-top and I wanted someone to tell him that just because it was Christmas it didn't mean he had to go over the top as if he was in panto at Blackpool. This is maybe a bit harsh but in the series he tends to get a mix of this and quieter stuff to work with to act as balance – for most of his short time here he does rather overplay it somewhat. Of course it works for the type of thing this special is aiming for but viewers who like their sci-fi to be a little darker will have been worried by his appearance in this manner – particularly coming after the slightly grittier turn from Eccleston. Piper continues to be as good as she was in her first season and it is to her credit that she does pick up well with her new co-star. Wilton Jones was good as the PM but Clarke's Mickey continues to grate somewhat.Overall then an good special that does the two things it sets out to do (entertain the family and get the new Doctor in the door and settled before the new season starts) and does it in a reasonable good way even if no one part of it is done really well. Fits well with the tone of the season that followed it though.

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.
