This is a great documentary drama, except for the constant bad language of the narrator, Gina McKee.
McKee has at least as big a bad language problem as George W. Bush. Neither Bush nor McKee can say "nuclear": Both say "nucular". And, if anyone tells you that is not bad language then do not believe them.
For an actor, or journalist, or what ever McKee is, a single word mispronounced in a show might be forgiven. However, this is bad constantly. The narrator can not avoid it, especially as the subject is about the prospect of "nuclear" war so the word comes up constantly.
However, after the Producer (Henry Chancellor) and Executive Producers (Taylor Downing and Sam Organ) and/or almost anyone else involved had spoken to McKee about the project, and done nothing, then they become equally responsible for the bad language.
What if a show is about writing a book, and the narrator constantly talks about the "wroter" of the book? Or, about elephants and the narrator calls them "efalants". Or, about television and the narrator says "telovision".
This show deserves a re-dub, to take out the constant bad language of the narrator, Gina McKee.
Otherwise, it scores 8-9.
