Marc Savlov · Austin Chronicle 89.00/100.00

Anything but dull, Gibney’s clarion call whipsaws along like a combo Jason Bourne/007 thriller minus all that running. Unnerving and likely to give viewers some bitter food for thought, Zero Days is Gibney’s most important work yet.

Godfrey Cheshire · RogerEbert.com 100.00/100.00

Easily the most important film anyone has released this year, it is a documentary that deserves to be seen by every sentient citizen of this country – and indeed the world.

Justin Chang · Los Angeles Times 90.00/100.00

Gibney’s film cuts across subjects and genres with its own fluid, quicksilver intelligence.

Soren Andersen · The Seattle Times 88.00/100.00

It’s a detective story. It’s a spy thriller. It’s a cautionary tale. And it’s true.

Joe Morgenstern · Wall Street Journal 80.00/100.00

You’ll want to see Zero Days — just not when you’re counting on a good night’s sleep a few hours later. Alex Gibney’s documentary about cyberwarfare is many things, none of them lulling: a thriller, a detective procedural, a startling chronicle of science fiction transformed into fact, and an urgent plea for public discussion of a new way of waging war that could wreak havoc on a scale akin to that of nuclear weapons.

Stephen Holden · The New York Times 90.00/100.00

Zero Days has a similarly balanced outlook along with a critical political viewpoint that avoids hysteria and demagogy. Its strongest protest is against what Mr. Gibney sees as the dangers of excessive American secrecy.

Peter Bradshaw · The Guardian 80.00/100.00

Zero Days is an intriguing, disturbing watch.

Jessica Kiang · The Playlist 83.00/100.00

His new film Zero Days may ostensibly be an investigation of the 2010 malware worm known as Stuxnet, but over its swift-moving 116-minute runtime, Gibney does a much broader and more important job: relating the rather airless, abstract concepts of cyber-terrorism and internet espionage to their real-world consequences.

Peter Debruge · Variety 90.00/100.00

Clear, urgent and positively terrifying at times.

synced 2026-07-25
Giovanni Marchini Camia · The Film Stage 91.00/100.00

What Zero Days lacks in subtlety and formal innovation, however, it compensates for in breadth and lucidity.
