Alex Garland is responsible for some of my favorite movies ever -- 28 Days Later, Never Let Me Go, Annihilation. Hell, I even liked Men. (That was a comedy, right?)
But Civil War is something I can only describe as actively stupid. It's the filmic equivalent of a college freshman realizing that the media is only interested in violence, man!
There is political violence, drained of all politics. There are bizarre decisions made by the characters -- let's take an aging man into a war zone, just for lulz!
And in an age where journalists are routinely targeted by militaries around the world, there are many naïve scenes where the characters grasp their little PRESS cards and are all of a sudden adopted by different military units, or invited to witness atrocities that they would more than likely be trying to cover up.
And why are they, sometimes, still shooting on film?
This movie is awful. It makes no sense. The ending is not nearly as clever as it seems to think it is.
