Of all the moments on this list there is one that sticks out as so shocking, so against the show's traditional code of conduct, that it cannot be beaten on the darkness factor. The moment in question is no doubt the scene where the Doctor tries to strangle his companion, Peri. A newly-regenerated Sixth Doctor (whose predecessor was so lovely he wouldn't strangle a fly) is feeling a bit under the weather after his rebirth - by which we mean he has gone stark raving bonkers. Growing paranoid, the Doctor starts to believe that his companion is an alien spy. "Well, we all know the fate of alien spies", he says before attempting to strangle Peri. Only his own reflection in the mirror makes him come to his senses. There is some parallel between Peter Capaldi and Colin Baker's Doctors, as it seems both will be the reckless, unpredictable incarnations who are meant to be a bit hard to like. However, you can imagine that the production team will learn from the mistakes of the show's past and never include as dark an introduction to the new Doctor as this one. To conclude, the 'Is he a good man or isn't he?' campaign is a good attempt to get people excited - and perhaps get the fans a little worried - about the new Doctor, but in truth it's not really needed. Peter Capaldi's Twelfth Doctor will in fact be just like all the great Doctors before him. A man at once weary of his old life and raring for adventure, someone full of kindness but also great fury. In short, he won't be the 'dark' Doctor, he'll be the Doctor. And that's enough to get excited about. Are there other dark moments of the Doctor's past that we've forgotten? Do you actually think Capaldi will hit a caveman over the head with a rock? Materialise your thoughts in the comments section below!
