This is the first “small” episode we’ve seen the show do all season, so perhaps it’s not surprising that there’s only a small amount of promotional pictures to go with it.
And as has been emphasized greatly this is a “found footage” episode. I had thought that maybe that meant it would end up a bit like “Blink,” and be Doctor and companion-lite. But that doesn’t seem to be the case. It seems to be just a framing device.
There also seem to be two sets of people who are investigating. The Doctor and Clara, and then the uniformed set of people, played by Elaine Tan and Neet Mohan.
I assume they will have different end game plans for what’s going on here.
(I also assume they’re probably fodder for the monster of the week.)
And though there will be “horror” monsters, I think Reece Shearsmith (whose character name is Rassmusssen) is the real monster here.
And I think we should all be very worried about this.
So are the horror monsters real? Or are they hallucinations due to lack of sleep?
