Dalek

Absolutely magnificent!

This was not only comfortably the best episode of the new series but, quite possibly, the best Doctor Who story ever - and I know I'm not the only one to say that. In exploring the allegorical potential of science fiction, the episode took up the gauntlet thrown down so dauntingly by the likes of the new Battlestar Galactica and beat them at their own game. We were shown the Doctor as refugee (and, perhaps, war criminal) a man (alien?) struggling to come to terms with his own past and, in his torment, posing some serious questions for our own world.

There is no need to rhapsodise at length about the tautness of the plot, the excellence of the special effects or, even, how well Billie Piper performed as Rose; others have covered that ground and said nothing with which I would disagree. For me, it was the overwhelming sadness of the episode that ensured its classic status. The moment when the Dalek learned that he was all alone in the universe was genuinely moving. And has the series ever produced a finer moment of acting than Christopher Ecclestone's utter devastation in response to the Dalek's "You destroyed us"? The actor conveyed perfectly the Doctor's realisation that he, too, was a mass murderer, no better, and probably worse, than the creature he was so violently taunting.

But even that was topped by the Dalek's melancholy response "You would make a good Dalek" to yet another of the Doctor's bile-filled rants. How easy it would have been to make that line a flippant throwaway, an infantile "one-liner" with an instant, and unsatisfactory, payoff. Instead, it added a bleak resonance to the Dalek's earlier remark that he and the Doctor were alike. The Dalek had meant that their loneliness united them. In fact, as the creature came to understand, the common ground was irrational hatred.

At such moments, the programme was much more than an entertaining piece of fantasy hokum, but a profound exploration of the human condition. Of course, such existential speculation has always been begged by a series with the title Doctor Who; many more episodes like this and they're going to have to start writing it with a question mark.
