10 Chilling Doctor Who Unsolved Mysteries
6. The Midnight Entity
In a universe filled with aliens, monsters, robots, and gods, Midnight proved that the most frightening force of them all is ordinary people.
After the Tenth Doctor boards a bus on the titular planet, he and the other passengers become the playthings of an unknown entity. It rips the front of the vehicle off, killing the driver and the mechanic, then stalks the others by banging on the walls. It eventually finds its way inside by possessing one of the tourists, Sky Silvestry, before freaking everybody out to high heaven by repeating everything they say.
Midnight is a masterpiece of suspense, terror, and self-examination, and it's made even better by the fact that nobody knows what the creature at the heart of it is. It's never seen, never heard, and never explained. Even the Doctor is baffled by how it can exist on such a hostile world, full of deadly radiation.
Some fans believe the entity can be glimpsed, ever so briefly, as the shield on the windscreen goes down.
But whether or not the production team did leave us something to find, the reality is that the truth about the entity will never be revealed – and nor should it. Its power lies in its mystery.
