    This isn't an actor's series, really—aside from Mr. Pegg, the cast is a delivery system for the plotline. But Mr. Rylance brings a bit of the blood to a smartly clinical, cynical, and all-too-believable story.

    [An invisible cyberwar with Russia is] a terrifying prospect, and one that he [creator Peter Kosminsky] has brought pretty effectively to the screen without succumbing to the temptation to make the main characters swashbuckling or glamorous.

    Broad in scope and rarely letting go of its in-built tension, The Undeclared War feels like a fresh take on political drama.

    This series exceeds expectations, guiding viewers by the hand through the complex world of cybersecurity - and then refusing to relinquish its grip until the final episode.

    The Undeclared War sports good lead performances, some creative storytelling and a plot that steadily builds tension. And we don’t have to look at that much code, which is a plus.

    Timely if sluggish and ultimately unfocused, The Undeclared War amounts to a dramatized stress-test of GCHQ in the face of triple-tier malware, CC TV hacking, and deep-fake media.
