10 Most Insane Storylines In Doctor Who

2. Utopia/The Sound Of Drums/Last Of The Time Lords

Meanwhile, the three-part finale to the third series had been just as utterly loopy, in its own way. Kicking off with the fantastic €˜Utopia€™, which featured the incredible Derek Jacobi and the return of the Master in the closing seconds, this episode was one of the very greatest that the new Doctor Who had ever produced, imaginative, scary and genuinely dramatic. Then things go pear-shaped, when the Master arrives in Britain to become the new Prime Minister, and makes a deal with the future remnants of the human race, a race he nicknames the Toclafane (essentially, cannibalistic severed human heads inside flying spheres covered in razorblades and death rays that speak in the voices of mad children), to invade 21st century Earth. The 10th Doctor is aged prematurely (for some reason) and then de-aged in the final episode, when he reverses the effects of the invasion and stops the Master, who is shot and dies in his arms, having refused to regenerate out of some kind of childish fit of pique. Finally alone, having saved Earth yet again, the Doctor is ruminating on things in the TARDIS, when the Titanic crashes through the wall of the control room. Yes, that€™s the cliffhanger: what appears to be the actual Titanic ocean liner crashes into the Doctor€™s semi-sentient space/time travel headquarters.
