High Points

I really wish there was one.

Low Points

Okay so there’s a reason, but… the entire episode.

The Scores

Originality: The story twist is something I’ve not actually seen before. It’s got familiar elements, but it combines them in a new way. 5/6.

Effects: Disappointing. Some good things, mostly helped out by the generally low lighting throughout the episode, but a very cheap-looking climactic scene and a sad mixture of good and utterly terrible computer UIs. 3/6.

The story twists and turns and attempts to deliver surprises and be scary, but completely failed for me. The weird stuff doesn’t build up with any sense of tension, there are inconsistencies all over the place that the characters don’t catch on to until it’s time for the big reveal, and when that comes it’s pretty disappointing. I really do expect better from Mark Gatiss. 2/6.

The acting is so-so. Having come from Capaldi’s passionate performance in the previous episode, this one really feels like an episode where everyone’s coasting a bit. We know at least two of these actors are better than that though, and given the story’s limitations there’s really only so much anybody could do. 3/6.

The emotional response just wasn’t. 1/6.

Production: dark corridors with odd cross-sections. Very strange camera angles, with an in-story reason of course – this is meant to be ‘found’ footage – but it doesn’t actually feel like that. And there’s an in-story reason for that too, but it doesn’t erase my underlying sense of dissatisfaction. 2/6.

Overall: I’ve been told some people thought this was really good. I disagree. I watched it, I thought it was mildly interesting, but this is definitely the weakest episode of this series so far. 2/6.

In total, Sleep No More receives a hugely disappointing 18/42.
