I’ll be blunt.
I didn’t like it.
I applaud the experimentation, but when it boils down to it, the ‘found footage’ thing added absolutely nothing to the story. It made no sense and it would probably have been a better episode without the conceit.
I found the premise hackneyed and unengaging and the ‘twist’ was signposted so thoroughly, it was barely a twist at all. In fact it managed to wipe its own twist out by first of all claiming that the dust motes were acting as cameras (big scary revelations!!!) then to have Reece Shearsmith’s character say he made it all up. No one cared, Reece. no one cared.
But the thing that annoyed me most of all is that this was basically a rehash of an earlier episode (Under the Lake/Before the Flood) where a unengaging military types run up and down corridors attempting to evade a lumbering conceptual monster . . . yawn yawn yawn yawn yawn.
We also saw the return of Moffat’s obsession with seeing something ‘in the corner of your eye’. It reached ludicrous levels though with villains made of congealed sleepy dust.
I’m actually finding it difficult to say anything positive about this episode. It was ‘blah’ at best; a huge surprise coming from Mark Gatiss who has written some of my favourite episodes of New Who. This though, was the first serious misfire of the season.
Still . . . not as bad as Kill the Moon.
And the slow disintegration of Rassmussen at the end of the episode was cool, but a bit Arnold Vosloo.
And Chopra was very pretty.
Otherwise, I’m sad to say, it was but Filler. Nothing more.
