‘You must not watch this. I’m warning you. You can never unsee it.’ Mark Gatiss steers away from classic Doctor Who homage to do something more like an episode of Inside No. 9 – an impression unavoidably suggested by the presence of his fellow Gentleman Reece Shearsmith. It’s a pastiche of found footage horrors with a very No. 9 twist. And that’s about all there is to it.

It’s almost a shame this wasn’t an Inside No. 9 crossover, because it would have worked much better as a tight half hour. There simply isn’t enough incident for 45 minutes, and I found my attention wandering at various points despite some decent monsters, a mid-episode climax as the space station begins to plunge towards Neptune, and a load of visual effects to keep things from becoming too Talking Heads. The end result isn’t an unmitigated disaster, but it needed some bigger moments and better scares to hit the mark.
