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.

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

In sanding down some of the edges, the show has lost some of its urgency – along with its sense of dread about the state of the world. .... But it now feels like a drama that appreciates that no catastrophe is as compelling as one driven by intimate, human stories.

More of an intellectual thriller that tries to get pulses racing by watching code upload. [29 Aug - 11 Sep 2022, p.7]

When The Undeclared War ratchets up the tension of that possibility, it’s relatively gripping. It’s too bad, then, that the rest of it is content to shuffle along at a snail’s pace, taking us down detours and refusing to engage more deeply with its political concerns.

The central mysteries of The Undeclared War – who’s behind the cyberattack, and what are their intentions – may be enough to carry you through. The series is at its best when it’s ratcheting up the tension. Just don’t expect it to convince when it comes to anything deeper.

An experience that is both meandering and mundane. For every scene that feels a bit sharper, there are multiple that are painfully dull. For all the many contemporary connections it lays out, its superficial story remains largely detached and directionless.

This is drivel. A product of staggering ineptitude. The series repeatedly introduces dramatic personal storylines that have little impact on the central conflict. They consume screen time without developing the characters or advancing the plot. The main character has zero agency. After the first episode, where she catches something her coworkers (unfathomably) did not, she has no actual influence on the plot. The plot is happening to her instead of through her. The show pretends to be about cybersecurity, but repeatedly sacrifices technical plausibility for dramatic convenience. Major plot developments rely on fictional capabilities and unrealistic depictions of programming that ultimately break the suspension of disbelief. The acting does little to salvage the writing. Aside from the two Russian lead characters, most of the cast deliver forgettable performances, and the protagonist is particularly jarring.
