This movie follows a group of journalists and photographers as they travel across a United States ravaged by civil war.
First off, the trailers make this more of a film focused on the action and battle movements, while this is actually a more measured piece that focuses on the journalists' journey. This is written and directed by Alex Garland (Ex Machina, Men) and if you've seen his Annihilation, this is kinda the same formula (a group on a journey) minus the sci-fi. When the action happens, it's well executed but the core of the film is a lot of showing and talking about the situation.
Don't confuse this being plot heavy for this being a boring movie. Far from it. This reminds me a lot of The Big Red One in that this is a travelogue looking at the madness of war that is composed of various thematic elements. This movie does a solid job of changing gears from the eeriness of desolate, war-torn America to dark comedy to moments of real tension. Civil War has one of the most gripping, suspense scenes I think I've ever seen.
The main focus of this film is on the musings in the last few years that the United States could go to war. This has a real world message in that an ACTUAL civil war in the United States would be a terrible, bloody thing that'd pretty mess up most people lives.
For those radicals arguing in favor a civil war, this movie also makes a point that having one in a place as vast as the United States wouldn't be a single concentrated effort. (In this movie we've got factions and smaller rebel groups.) A lot of people may want the Democrats toppled, but how much you wanna bet they all don't have the exact same view on the government that comes after or what they want or what the real threats are? (Did you see the footage of the gathering assembled to stop immigration at the border? There was some infighting between individuals and factions).
The movie also a well-written look at what it is like to be a journalist during war.
Garland makes the scenario audience-friendly (and more importantly audience-money-friendly decision) by not to base this movie off of any real world politics. Texas and California are in an alliance and that ain't happening in the real world (maybe parts of rural California but not all of California). Garland does an interesting job of laying out the hints of how the civil war came without straight up directly telling the audience exactly what went down.
In terms of visuals and audio, this is pure "cinema." The cinematography is excellent, featuring well-placed camera work and a strong design sense with what is undoubtedly going to be considered one of the most hauntingly beautiful movie scenes of the year. I do not have discerning ears, so audio work doesn't usually stand out to me. Not here, though. I won't go into detail, but prepare for some of the most effective movie sounds in a while.
Kiersten Dunst delivers what is probably one of the best and most distinct performances in her career as main lead photojournalist Lee. She is a cool-headed, hard-headed veteran of war coverage. Dunst really manages to deliver an objective and hardened, but human-beneath-it-all individual. Also really good in this is Dune Part One's Stephen McKinley Henderson as journalist Sammy, the eldest and wisest of the group. I noticed that the guy's stock in in the film world has gone up in the last ten years or so, because he does a quality job as an authoritative but approachable person.
If there any possible flaws to this film, some may find the final act to run a bit long.
Highly recommended, this is such a well-constructed film. Garland delivers his first movie that isn't sci-fi (or whatever genre Men was supposed to be), which has resulted in his most accessible film.
