‘Civil War’ Review: We Have Met the Enemy and It Is Us. Again. (2024)

A blunt, gut-twisting work of speculative fiction, “Civil War” opens with the United States at war with itself — literally, not just rhetorically. In Washington, D.C., the president is holed up in the White House; in a spookily depopulated New York, desperate people wait for water rations. It’s the near-future, and rooftop snipers, suicide bombers and wild-eyed randos are in the fight while an opposition faction with a two-star flag called the Western Forces, comprising Texas and California — as I said, this is speculative fiction — is leading the charge against what remains of the federal government. If you’re feeling triggered, you aren’t alone.

It’s mourning again in America, and it’s mesmerizingly, horribly gripping. Filled with bullets, consuming fires and terrific actors like Kirsten Dunst running for cover, the movie is a what-if nightmare stoked by memories of Jan. 6. As in what if the visions of some rioters had been realized, what if the nation was again broken by Civil War, what if the democratic experiment called America had come undone? If that sounds harrowing, you’re right. It’s one thing when a movie taps into childish fears with monsters under the bed; you’re eager to see what happens because you know how it will end (until the sequel). Adult fears are another matter.

In “Civil War,” the British filmmaker Alex Garland explores the unbearable if not the unthinkable, something he likes to do. A pop cultural savant, he made a splashy zeitgeist-ready debut with his 1996 best seller “The Beach,” a novel about a paradise that proves deadly, an evergreen metaphor for life and the basis for a silly film. That things in the world are not what they seem, and are often far worse, is a theme that Garland has continued pursuing in other dark fantasies, first as a screenwriter (“28 Days Later”), and then as a writer-director (“Ex Machina”). His résumé is populated with zombies, clones and aliens, though reliably it is his outwardly ordinary characters you need to keep a closer watch on.

By the time “Civil War” opens, the fight has been raging for an undisclosed period yet long enough to have hollowed out cities and people’s faces alike. It’s unclear as to why the war started or who fired the first shot. Garland does scatter some hints; in one ugly scene, a militia type played by a jolting, scarily effective Jesse Plemons asks captives “what kind of American” they are. Yet whatever divisions preceded the conflict are left to your imagination, at least partly because Garland assumes you’ve been paying attention to recent events. Instead, he presents an outwardly and largely post-ideological landscape in which debates over policies, politics and American exceptionalism have been rendered moot by war.
