"It's a great movie that has its own life force."
— Matt Zoller Seitz, RogerEbert.com
"A thoroughly engaging war drama that’s more about people than about politics."
— Tasha Robinson, Polygon
"Taken as speculative fantasy, however, Civil War is never less than vividly, chillingly authentic."
— Neil Smith, Total Film
"Frightening, even-tempered, and disarmingly humane, Civil War is intelligent precision filmmaking trained on an impossible subject."
— Rocco T. Thompson, Slant Magazine
"The constant onslaught of foreboding tension and stunning documentary style prowess in capturing the raw horror ensure a breathless, potent piece of filmmaking."
— Meagan Navarro, Bloody Disgusting
"Garland may have just delivered one of the most vicious and unrelenting watches of the year, one that I’ll keep debating and untangling both in my head and with others for a good long while."
— Matt Donato, Collider
"Civil War delivers a challenging, thrilling, heart-pounding movie about the importance of journalism in times of conflict, about how easily we become desensitized to violence when we’re living through it."
— Rafael Motamayor, IGN
"An upsetting sensory experience accompanied by thundering cacophonies and paralyzing scenes of war and savagery so vast, intense, and overwhelming that you can practically taste the gunpowder lingering in the air."
— Siddhant Adlakha, Inverse
"Alex Garland’s latest is wholly consuming. An epic but deeply intimate piece that uses the experience and motivations of a group of military-embedded journalists to highlight the deeply chilling reality of living in a world that never learns."
— Perri Nemiroff, Perri Nemiroff (YouTube)
"While bound to spark hundreds of think pieces, Alex Garland’s stirring Civil War will undoubtedly go down, too, as one of the most provocative films of the year. It’s also an early contender for one of the best, offering a stunning warning: no matter what the cause, war is hell."
— John Fink, The Film Stage
"The film does not have easy answers, but rather than making it seem shallow, its lack of clear moral coding instead offers us something more primal and more powerful. It’s a film about the open-ended question of how much humanity we as a species have left in us, and that makes it a provocative, thrilling monster of a movie that will sear itself into your eyeballs."
— Matthew Jackson, The AV Club
