First of all, this series did not strike me as being particularly 'woke', nor did I witness any aspect of the series that remotely resembled 'leftist propaganda'. This is a show that depicts politicians and GCHQ staff who don't all happen to be male and white. Some are, some aren't. That's all. In fact, I would go so far as to say that the writers seem to have made a genuine effort to avoid political or ideological bias altogether. At its heart, it is very much a character-driven story that doesn't concern itself with hidden agendas.
Be that as it may, 'The Undeclared War' is a Mini-Series not without it's flaws. A few instances of below par acting and the occasional minor plot hole prevents it from making its ascension into the very top tier of television, but it ultimately succeeds in achieving what it intends to achieve - telling a story as nuanced as it is engaging, whilst borrowing just enough source material from the political reality we all know well to present itself as a compelling and thought-provoking warning call to us all.
Even in light of its flaws, 'The Undeclared War' most certainly achieves what it intends to achieve. It doesn't quite achieve what it promised to achieve, however. It doesn't work quite as hard as say, the BBC's 'Years & Years' did, to hook its audience with the type of emotional depth and innovative dynamism that leaves their tears destined to fall and their jaws destined to drop. Nevertheless, its carefully developed storyline, sharp dialogue, and explosive plot twists ensure that it still achieves just enough to merit a solid 7/10 rating.
