Doctor Who: Peter Capaldi’s 9 Coolest Stand Alone Episodes

Occasionally, Doctor Who gives us a horror story which is also a head-f**K, and here is the prime candidate of Peter Capaldi's run. Sleep No More opens as a standard open-and-shut story, but quickly morphs into something decidedly weirder.

If you thought that Doctor Who wasted the superb acting talents of Reece Shearsmith on such a jittery simpleton of a character, then make sure you watch the episode right through until the end. Turns out audiences and characters were duped alike. Watching him stare directly at us until he melts into a sandy apparition, is sufficient to scare any young child witless, and probably a fair few adults too.

What's also great is that The Doctor pretty much loses. Sussing the problem is a prerequisite for him, but not this time. He exits the episode confused as hell and there is no more closure beyond that. This wasn't lazy writing. It just added to the overall creepiness. The resolve is so bizarre, it almost didn't belong in Doctor Who, which is exactly why it 'did' belong.
