At the end, the character development becomes terrifying, when he decides that as the last Time Lord, it is up to him to make the laws of time... culminating in a character's suicide. "I've gone too far!" From there on, he has to die. He thinks he is a god... there is nowhere he can go from there, except redemption and death.
When it comes to New Who finales, there has always been, so far, a build-up to a big bang of a story, hints spread throughout the earlier episodes, ending with something huge - and inevitably even more danger than the last year's story. Series one there were Daleks way into the future. Series two, Torchwood was identified, and both Cybermen and Daleks materialised into the here and now from a parallel world. Series three, the Master became Prime Minister of Britain, Master of the world, decimated the world's population (but at least he used the word literally) and it became a terrifying, barren planet. "Planet Earth is Closed." Series Four ended with Daleks, Davros and the world being moved for some nefarious purpose I can't remember but that was so desperate that a better alternative was to blow up the planet. And Series Five, or the Specials, if you prefer, finished with the return of Gallifrey, the Time Lords, and the revelation that the Time Lords wanted to bring an end not just to the world, not just to the universe, but to time itself.
Matt Smith looks wonderful, a more classic-style Doctor, reminiscent of Jon Pertwee, with a bit of Tom Baker thrown in. A young actor - only three years older than me - but supposedly playing the character as a much older man. Polite, quietly-spoken, with a real sense of adventure. His companion, Amy Pond is Scottish, ginger and young. I am a bit worried about her, in a way. She seems too young to my eyes. She is described as "feisty," which is all very well, but I'm hoping there is more character depth than some possibilities. It is all too easy to designate a character as "feisty" to make sure they're interesting, and for it to mean little more than "argumentative." Then again, that was what I first expected Catherine Tate's Donna to be like. We will wait and see.
In the absence of a sofa in the house, it is time for me to position myself behind the armchair...
