"Kerblam!"

It's called "Kerblam!", which, depending on one's mood, is either delightfully chipper or just plain silly. The story is one of Doctor Who versus the evil corporation, something which has, of course been done several times before. It's a story that could fit in any era of modern Doctor Who, perhaps even (finer details aside) in an 80s episode. As, with many other writers this century, Pete McTighe is an avid Doctor Who fan, but seldom has a a writer’s joy in being given the chance to pen an episode of their favourite programme been more evident than in interviews with McTighe. This joy transfers to the story and it is this which elevates a run-of-the-mill Doctor Who plot into something more.

The obvious real-world equivalent of Kerblam! is Amazon and it would be all-too easy to attack a large corporation for being oppressive, but Pete McTighe does something more subtle. Kerblam! takes pains to ensure that it's employees are well looked after and their break area is a really nice park. The Kerblam! Management always have their underlings' best interests at heart. Even rebukes about employee productivity are delivered in a friendly manner. However, McTighe seems to make the observation that such environments are intrinsically oppressive, no matter the intentions of the higher echelons. The detrimental effects on employees and general employment are clearly evident, but the fact that the villain is a someone who is doing it for the benefit of those workers, is beautifully subversive. Added to this, the villain's plan being turning the power of the corporation against itself and the Doctor saves the day by turning that back against the villain is glorious. Even the blatant plot-delaying tactic (Twirly running out of power) is forgivable as the reason Twirly does that is that he wastes time and power up-selling.

The supporting cast is wonderful. Julie Hesmondhalgh is a phenomenal actress who puts her all into the role of Judy. Leo Flanagan makes Charlie a very sympathetic mass-murderer and Claudia Jessie makes Kira sweet, when she could have been cloying and her death is suitably heart-breaking. As the surprisingly short-lived Dan, Lee Mack is very likeable. The regulars all shine in the best ensemble work that they've been given and we have our leading lady. The Doctor is authoritative, inventive and sympathetic – yet her glee at receiving her Kerblam! Parcel is very infectious. The visualisation is very like a Sylvester McCoy story with a colossally higher budget – visual similarities with The Greatest Show in the Galaxy are obvious. Yet we have such stunning scenes like the conveyor-belt chase which show director Jennifer Perrott in complete command of the material.

With nearly every element being honed to perfection, "Kerblam!" is an unalloyed delight and I hope Mr McTighe returns to pen another adventure, soon.
