Doctor Who (2005) - S10 • E4 Ratings & Reviews

"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.
SFX Magazine
Zoe Delahunty-Light
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.
Houston Press
Jef Rouner
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.
Nerdist
Kyle Anderson
I still think this episode was effective, and even if the ending wussed out, it managed for the most part to be a good representation of a variety of horror that the BBC does so well.
Radio Times
Patrick Mulkern
For the first 35 minutes or so of Knock Knock I'm enthralled. Unfortunately, it show signs of collapsing like a souffl during the denouement.
Daily Mirror (UK)
Daniel Jackson
Knock Knock wins on quite a few levels - direction, effects, atmosphere and the expected brilliance of Capaldi and Mackie. But it's a weak storyline that just isn't given space to breathe.
TV Fanatic
Kathleen Wiedel
Over the years, Doctor Who has excelled at turning the ordinary into the extraordinarily creepy: statues, shadows, cracks... Doctor Who Season 10 Episode 5 added creaky floorboards to the ever-growing list.
Slant Magazine
Steven Cooper
It's good to have what seemed like a straightforward "monster" story turn into something with more emotional complexity to it.
Observer
Noam Cohen
I think it's about time to call it: This season of Doctor Who is shaping up to be a real yawn.
New York Magazine/Vulture
Ross Ruediger
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 ...
Daily Telegraph (UK)
Michael Hogan
From creaking floorboards to claps of thunder, whistling wind to slamming doors, this knowingly nostalgic episode was styled like an old Hammer horror flick.
Screen Rant
Kevin Yeoman
As much as the hour hinges on Suchet's turn from malevolent landlord to weepy mama's boy, "Knock Knock" is also interested in being an early turning point of the season.
IGN Movies
Scott Collura
"Knock Knock" is a nice mix of horror, humor, and monsters of the week (space fleas!) amid an ultimately tragic tale about what happens if you can't get on with your life and let nature take its course.
Guardian
Dan Martin
Another cracking story in a series yet to drop a dud.
Entertainment Weekly
Nivea Serrao
David Suchet, who's been bringing Agatha Christie's Belgian detective Hercule Poirot to life for years, finally got to play the other side of the mustache, as he gave a wonderfully spooky performance as the Landlord.
AV Club
Alasdair Wilkins
Doctor Who has something special in Pearl Mackie and Bill... When she's accompanied by Peter Capaldi and David Suchet at the height of their powers, it's easy to forgive "Knock Knock" a bit of narrative wonkiness.

My favorite of the run so far, this one.
