Doctor Who: Series 8 Ranked From Worst To Best

2. Flatline

"Could you not just let me enjoy this moment of not knowing something? I mean, it happens so rarely." - The Twelfth Doctor

The Twelfth Doctor took the backseat in Flatline as Clara Oswald stepped into the spotlight to take on a new menace from another dimension. With our Time Lord trapped inside a shrinking TARDIS (which seemingly affected the relativity of his haircut, too...), his ever faithful companion took it upon herself to singe-handedly embark on an epic adventure which would defy the dimensions of reality itself. What followed was a spine-tingling story which built upon Doctor Who's acclaimed and established mantra of transforming ordinary household objects into the most terrifying of threats. In light of this, the episode no doubt resulted in millions of children - and probably lots of adults, too - being left petrified by the thought of Boneless creatures dwelling within the walls of their bedroom. That is, of course, one of Doctor Who's unique selling points, when it is successful in traumatising an entire generation. Somewhere out there, Steven Moffat is stroking a white cat called Tibbles and laughing. Speaking of the Boneless, these two-dimensional terrors will no doubt go down in history as one of the Twelfth Doctor's most terrifying foes and the special effects team deserve a special mention for realising their spine-chillingly static appearance. With its final and atmospheric showdown in the underground, fans have also taken their hats off to the writer, Jamie Matheison, who returned from his Orient Express escapade to deliver a creepy adventure which had all the ingredients of a Doctor Who classic. He also deserves credit for being able to make the Doctor such a strong presence throughout the episode, despite the fact he spent the majority of its proceedings confined to the depths of Clara's handbag. And no, that's not a euphemism! The episode also featured the Doctor dancing, which is always a treat.
