This is outstanding! Head and shoulders above the rest of the series with an ingenious premise and an exciting conclusion.

It’s Doctor Who meets The Office, with much of the dialogue pulled from mid-2000s office talk (including the terrible jokes). This is a very engaging and surprising setting for a sci-fi show. Then you get the big reveal - all the staff, including Lucie Miller who has been headhunted, have been hypnotised to perform their boring office jobs in aid of a mercenary army core. This reveal absolutely knocked me off my feet. Impeccably done.

To top it all off you then get the Cybermen making a genuinely surprising appearance at the end!
