    This series deserves your time.

    The elephant in the room is that the subject matter of this series is very relevant and real. For those people who don't understand how the world works, this has probably flown over their collective heads. Yes, it's a drama series, but it's done very well. This is tight, clever, thought provoking writing. In today's ever changing world, it's refreshing to see something that takes chances and delivers. This definitely deserves your attention. Highly recommended.

    So many negative reviews!

    Seeing all the negative Reviews for the show I thought I would come on here to give my two cents. I found it on the Undeclared war to be gripping thriller so much so that I finished the whole season in one night. Hannah delivers a great performance along with Simon Pegg. One not to be missed!

    Startlingly accurate. Ignorant reviews abound, but still I fear the worst.

    I don't know who these types are that are calling this show 'Inaccurate'. They certainly don't work with software!

    I'm just bowled over by the accuracy. The whole setup, and the tech, is completely believable and obviously researched. Simon Pegg's influence? (Probably not, he's not a producer on this.)

    The physical metaphors with corridors and walls and doors are essential, and I'm quite enjoying them - laypeople have NO idea what it looks like going through dense code. Especially slogging through code that's written by somebody else, let alone an adversary. This visual storytelling mechanism greatly eases things.

    Also the portrayals of high-functioning Autism are, finally, actually right on the money.

    But I'm only two or three episodes in, and I fear it is going to dissolve into mush. None of the characters are very likeable, but perhaps that's deliberate. The mains all ooze upper-class UK elitism, and the lead character trots out her religion whenever it suits her.

    We'll see.

    Ingenious depiction of terrifying events

    Let me start by saying that I admire Peter Kosminsky's work. Wolf Hall garnered much praise and I thought that The Promise was one of the best things I have ever seen on television. So I had very high expectations of this series.

    By that benchmark this was a disappointment. Yet the storyline is ingenious, depicting terrifying events that might just be plausible and certainly act as a timely warning in this world of fake news and cyber warfare. So why the disappointment? I have a few quibbles, such as the sudden ending and the self-blame by the main character ringing false. But in reality it is because I wanted to watch a series that merited a score of 10, not a 7!

    I will hope for something truely outstanding from Mr Kosminsky with his next venture ....

    I feel like something is missing...

    Mark Rylance is exemplary in this, as always.

    I can't help but feel as though it was a little unfinished... Perhaps it's me, I thought the ending needed to be more clear cut.
