From what I've read, the focus of this show is mostly about the training camp that the cast will be sequestered at. They are being told that the camp is on a base in Russia when it is in fact somewhere in rural England.
So it's still mostly about a bunch of chumps fighting over who did the dishes, and who has an alliance with whom.
Having a faked blast off at the end is a bonus though. Shades of <i>Capricorn One</I>; one of my favourite movies.
