I wake up in the middle of the night after drinking a little too much in a Paris cocktail bar. I’m on holiday. Dehydrated and unable to sleep for a little bit I stuck on Dalek, unaware that it was the 17th anniversary of this very story.

I was blown away by how subversive a way to bring back the Daleks it was. Dr Who gets to be the baddie and the (individual) Dalek gets to be the goodie, reflecting a shared trauma. As a result you get genuine character development and insight for both. The Time War has changed The Doctor.

It wasn’t just good on this level. I watched it go out live in 2005 with a group of school friends on a trip - we were 11/12. We thought it was the coolest thing we’d ever seen. Even a skeptical parent was won over “bloody hell, it never used to be this good!”

So many people were watching to see what the Daleks would be like in the 21st century and possibly would have been satisfied with a runaround. They were given so much more than that, an era defining story with a convincing portrayal of a damaged man meeting his old torturer.
