"The Zygon Invasion"/ "The Zygon Inversion"

Doctor Who very rarely “does politics” and, in the past, the results have been mixed. The Green Death managed to be an engaging story as well as informing the viewer on environmental matters and their political ramifications and The Curse of Peladon takes a look at an independent body joining a composite political entity that could be applied to EEC/EU membership. However, we also have the less successful likes of The Mutants in the 20th century and the ‘massive weapons of destruction’ which form the weakest part of the weakest story of the Eccleston era. "The Zygon Invasion"/ "The Zygon Inversion" immediately attracts, due to its irresistible title(s), but it also attempts to deal with some present-day hot-button issues - especially bearing in mind the events of 31 October and 13 November of 2015, chillingly close to broadcast. These aims have to hit their mark, especially now and the degree to which the story succeeds is completely unprecedented.

Following the events of "The Day of the Doctor", 20 million Zygons have assimilated into the human population. The overwhelming majority are peaceful, but a few of the younger generation are growing restless with the need to hide, to conform and have radicalised to form the group Truth or Consequences. The elder generation are appalled, but insist it is best for them to be dealt with by their own. It doesn’t take a genius to realise how much of this applies to radical Islam but the script by Peter Harness makes the issues easy to understand, without grossly simplifying them. Both sides spout hateful rhetoric, yet the viewer can understand the motivations of the characters spouting it. However, the dangers of radicalisation are only a part of the whole, for Harness and Moffat are just as keen on attacking modern warfare, indeed the entire concept of war itself. One abhorrent aspect of modern warfare that the vast majority of people just ignore or worse, accept, is the use of drones. Killing has become like a computer game, where, in a place of complete safety, operators can target images on a screen. Dehumanising the enemy makes their killing more effectively, and a dehumanised target is a faceless target. This story simply, yet devastatingly effectively, shows what happens when the faceless are given a face. Daniel Nettheim’s direction is unshowy, yet devastatingly effective in realising this and many other things. It takes a second to realise that the tumbleweeds in New Mexico are something more sinister and the dynamics of the Doctor negotiating peace with what looks like two little girls in a playground are fully explored for both incongruous comedy and grim drama. The Invasion of the Body Snatchers aspect of the Zygons is alluded to more strongly than ever before, most notably the 1978 version. It goes without saying that the production is fantastic, with the scene with the forced transformation of the peaceful Zygon being a deft mixture of the grotesque and the poignant.

The dialogue is brilliantly effective – the scene where the Doctor and Colonel Walsh have to give a pep talk to the UNIT soldiers follows a scene where they have a fundamental disagreement. Their speeches complement each other, yet do not betray their disagreement. However, it is in the key scene with the Osgood boxes that concept, dialogue, direction and performance combine to form one of the greatest sequences the programme has ever had in its 52-year history. War, the Doctor points out, is both preceded and succeeded by diplomacy and is the middle-man that needs cutting the most. Capaldi truly gives one of the best ever performances in the title role and, with the kindly smile he gives Bonnie, you can swear that you see all 2000 years of the Doctor’s life in his eyes. Jenna Coleman is great as both Clara and Zygella (sorry, Bonnie!) and we have the welcome return of Jemma Redgrave’s Kate and the brilliant Ingrid Oliver as, the far steelier, but still adorable, Osgood. We say goodbye, all to soon to Jaye Griffiths's Jac, but hello to Rebecca Front as Walsh - there is not a hint of The Thick of It when she and Capaldi share scenes.

"The Zygon Invasion"/ "The Zygon Inversion" doesn’t end with a bang, but neither does it end with a whimper. Zygella doesn’t betray the peace at the last minute and Kate doesn’t order UNIT to blow the Zygons up. What we have is better than a bang, a crescendo. "The Zygon Invasion"/ "The Zygon Inversion" is a story that I am tempted to throw superlatives at – ‘the best UNIT story since Inferno’ springs to mind. However, what I will say is this; there may be better stories than this one, but I cannot think of one that better shows how marvellous a programme Doctor Who is.

"The Day of the Doctor"

The anniversary specials of the programme have always generated interest, but Doctor Who in 2013 is a mainstream success in a way it hasn't been since Dalekmania in the 1960s. It is probably no exaggeration to say, therefore, that "The Day of the Doctor" is probably the most eagerly awaited episode of Doctor Who since "Rose". It has to satisfy the wide mainstream audience that will tune in, whilst keeping an eye on the fans, some of whom remember William Hartnell, some of whom were not even born when Christopher Eccleston was the Doctor. It has to pay tribute to the 50 years of television history that preceded it, whilst trying to tell an engaging story. It is a pleasure to state that the episode manages to succeed in all of these aims on a level that genuinely surprised even me.

More so than any of the other anniversary specials, "The Day of the Doctor" works as a regular Doctor Who adventure, this one being a fiendish plan by the Zygons to take over the Earth. The use of the pictures as suspended animation makes that part of the plot seem like a bright and breezy season opener, with the added bonus of featuring a well-loved adversary from yester-year. However, although the Zygon plot is easily enough to sustain a story in itself, taking place in two time zones and featuring a Zygon Good Queen Bess, this is only the gateway into a deeper story. For the pictures are relics of Gallifrey and of the darkest day of the Doctor's life...

The key thing the audience remembers from Anniversary specials is the current Doctor meeting with past incarnations and here, we have the very welcome return of David Tennant, playing the Doctor like he'd never been away. Joining him is the incarnation we must now call the 'War Doctor' played by the legendary John Hurt. I stated at the end of his era that I thought Tennant was the best leading man the show had had since Hartnell and Hurt is an acting legend, one of the finest in the world, who has always been thoroughly mesmerising in every role he has played. I can think of no better praise for Matt Smith than stating that he completely holds his own in the presence of Hurt and Tennant. Moffat uses the three Doctors more intelligently than his predecessors did – we really get a sense of the centuries dividing them. The War Doctor is definitely the warrior that his predecessor chose to be, but he has not made the key decision that has haunted his successors. It is also a good choice to have a previously unknown incarnation be brought to the fore – the War Doctor has no nostalgic connotations, so he can stand in for all the previous incarnations more effectively, which makes his criticisms of his successors' characteristics all the more potent. Some portions of fandom criticise the perceived modern overuse of the sonic screwdriver, which is alluded to by the War Doctor and then it is shown why the sonic is used so often, as, for the first time this century, the Doctor is locked up! The War Doctor initially has little respect for the flippancy of his successors, but it becomes clear that it is a coping mechanism for something he has not yet done. Little kisses to the past abound, from the title sequence to the fulfilled promise of all the Doctors making an appearance.

Nick Hurran manages to make the episode both completely epic, with the stunning fall of Arcadia and also very low key in the quieter moments. The 3D photography really serves the epic space battles well, but the episode never devolves into a mere 3D showcase. The design is opulent and contains great little touches – apparently the original version of Le Radeau de la Méduse contained no humans! Hurran assembles a great cast, with the very welcome return of Jemma Redgrave as Kate Stewart, a fun turn from Joanna Page as Elizabeth and her Zygon double. There is also the wonderful Ingrid Oliver as Osgood (related to a certain UNIT technician who assisted at Devil's End?) Jenna Coleman continues to sparkle as Clara, whether impersonating witches or out-thinking three incarcerated incarnations of the Doctor. However, there are two minor parts that made my jaw drop – a brief flash of Peter Capaldi's eyes and (possibly) the first uttered words of the Twelfth Doctor; and the return of the most iconic actor to play the Doctor in the 20th Century. Whoever the Curator actually is, it is a true joy to see Tom Baker again!

The decision to rescue Gallifrey may not be acceptable to some, but the way in which it is brought about is excellently constructed. Moffat wants to rescue the Doctor from the burden of committing the genocide of the Daleks and the near omnicide of his home planet. We found out the importance of the name of the Doctor and now we find out what must be done in that name. The emotional consequences are still there, as the Ninth and Tenth Doctors forget what the War Doctor did in his final days. The Doctor has had many titles given to him, but where once he was Death, the Destroyer of Worlds, he is now the more famous aspect of Vishnu, that of Preserver < / pretentiousness >. Moffat's script is superlative, writing and rewriting myth with aplomb, without losing the little touches of humour.

I remember "The Five Doctors" when the programme was in the autumn of its success and I also remember Remembrance of the Daleks and Silver Nemesis when the winds of winter were blowing. The story looks back at the programme's history, but makes sure that it does not rest on its laurels and makes a decisive step forwards into the future. In this November, 50 years after it started, "The Day of the Doctor" is another highlight of a glorious second summer that shows no sign of coming to an end. Long live Doctor Who!

Terror of the Zygons

Tom Baker's second season begins with his first alien threat against contemporary Earth. The basic storyline is nothing we haven't seen before- the Zygons want to conquer the Earth and use their cyborg monster, the Skarasen, to help them accomplish this. There are some plot problems, as we shall see later. However, if there is one story that is genuinely a 'triumph of style over substance' it is this one.

The Zygons themselves are one of the best realised alien races the programme has ever had. A fantastically designed costume is seamlessly blended with make-up onto the faces of the actors. Even today, a Hollywood budget would only slightly improve on the look. As in The Claws of Axos, there is an organic spacecraft, but one which is far easier on the eyes and far more subtle and interesting. All this is helped by Douglas Camfield's great skill in selecting the shots and supervising editing- the first full reveal of a Zygon is brilliantly done. Camfield manages to make the programme more 'edgy'- there is a real sense of danger in scenes such as the Zygon Harry's escape. Much has been made of the believability of the Skarasen. The creature is realised through a mixture of puppetry and a few shots with stop-motion animation. Although the creature is not particularly convincing, it is mobile and quite well designed. The end, where it rises out of the Thames fails mostly because it combines film and video elements- there have been far worse special effects on the programme.

The script is quite good, if somewhat half-baked. Despite the fact that the very first line by a Scottish character is aboot haggis, characterisation is good, with some nice moments. There is some clunky info-dumping- Broton explains things to Harry for no good reason, and some rather unbelievable plot points- the removal of the bug from the inn only alerts UNIT to where the bug came from and Sarah stumbles into the tunnel to the spaceship after being left alone by the Zygons, who have fetched a step-ladder for her to reach it. Any thought that they did that deliberately is scotched when they angrily discover the tunnel open.

The performances throughout are first rate, from Lillias Walker's spooky performance as Sister Lamont to John Woodnutt's excellent Broton/ Duke of Forgill. Tom Baker's detached, yet playful performance further distances the Fourth Doctor's personality from his predecessor. It's sad to see Harry go as a regular- Ian Marter made him entertaining and convincing throughout. This is also the last we'll see of the Brig for a good long while and Nicholas Courtney works his usual magic.

Terror of the Zygons has its problems, but it is thoroughly entertaining throughout and highly recommended.
