Critics Consensus

A bit of narrative weakness aside, "Knock Knock" is a wonderful mix of nostalgia, horror, humor, and monsters that culminates into a powerful and emotionally complex episode.

It's good to have what seemed like a straightforward "monster" story turn into something with more emotional complexity to it.

I think it's about time to call it: This season of Doctor Who is shaping up to be a real yawn.

Folks, we hit our first truly duff episode of the year. There's at least one every season, but let's hope there aren't too many more ...

"Knock Knock" is the first time in a very long while something on Who managed to actually scare me in more than just a particularly chilling concept.

Everything is bubbling below the surface, and I can't help but tremble with excitement as the next episode has an almighty amount potential stored up.

One, I am loving it. The writing is superb, and Peter Capaldi and Pearl Mackie make the best team since Sylvester McCoy and Sophie Aldred (Or, Paul McGann and India Fisher for my Big Finish Audio fans). I'm thoroughly enjoying that.
