Sapphire & Steel: Assignment One- Escape Through a Crack in Time, Part 6

 "Goodbye, Rob."

Probably best not to analyse this last episode too much; some stuff happens and we're back at the beginning, courtest of "The House That Jack Built". It's an entertaining spectacle, especially with Rob in the past as the house is being built, and all the storytelling beats are there... but it makes no real narrative sense. This episode feels oddly as though it's not so much a final episode but just a series of events in the shape of a final episode.

Again, no new cool concepts are introduced; this is about finishing things rather than throwing new ideas around. It all feels dramatic enough but there's a real vagueness to what happens.

This first serial, overall, introduces a mindblowingly good concept and throws loads of equally mindblowing ideas at us... but at six parts it's about a third too long, and most of the cool ideas are focused in the early episodes. This is what prevents what was a promising story from being quite as good overall as the early episodes seemed to indicate.

Still, overall this is a promising start. On to the next serial...
