This is a fantastically eery and suspenseful story; it's like a typical Doctor Who hide-behind-the-sofa episode, but in a spin-off rather than the main show itself. I love the concept of the Night Travellers (beings who steal your last breath) , and the use of the fairground music whenever the old film reel is being used is satisfyingly creepy, almost characterising the danger that the reel poses, a bit like how drum beats represent the Jumanji board game in Jumanji.

Those sequences when the people from the film reel come out of the big screen in the cinema is so cleverly done with the CGI work; it's sort of like watching a twisted version of Cinemagique from Disneyland Paris!

The Night Travellers MUST return in some form of Doctor Who or Torchwood fiction. They are EASILY one of the best monsters to come from one of the Doctor Who spin-offs; everything about them just oozes menace. They really capture your attention whenever they are on-screen, and they could easily come back in a Big Finish, a comic or in Doctor Who on TV, seeing as the end of the episode teases a return that so far has never happened.

Come on, Chibnall or Nicholas Briggs! Bring back the Night Travellers, one of you!
