10. Whenever They Fall Over
The Dalek design is immediately recognisable, and as iconic as the Doctor's sonic screw-driver, or the police box TARDIS, but naturally, the cumbersome nature of the beast makes them about as elegant as an elephant on roller skates. Frustratingly, over the course of the show's history, writers and show directors have failed to cover up the clumsiness - making a joke, whether conscious or otherwise - of the physical limitations of a villain that the Doctor genuinely hates and fears. The result is that fans question how anyone could justifiably recognise the threat of something that looks so ridiculous falling over, and that critics of the show invariably point out the stupidity of the Daleks' design, fundamentally and devastatingly reducing the characters' image. Here's a handy tip: just run away over some slightly rocky terrain and watch the cumbersome robo-dorks fall over with a hysterical lack of grace.
9. Would You Like Some Tea?
You'd think someone as committed to Dr Who fandom as Mark Gatiss would know not to mess with the Dalek formula, and to be honest his intentions to show the villains as duplicitous and deceitful is a good agenda, but not when that requires the Doctor's most enduring enemy to be a glorified maid. When Gatiss planned "Victory Of The Daleks," he clearly thought the idea of Daleks in disguise was a clever one - which it was - but he wrongly hoped, by his own admission, that them offering tea to war-time scientists and soldiers wouldn't be seen as a sketch - which it also was. Regardless of the intention, the sight of the devilish robots as slaves was not a welcome one for fans. For God's sake, at least poison it or something, or throw it into someone's face, scalding him horribly.
