Total masterpiece.
It would be stupid to waste time giving a back story to how they got into civil war, this isn't a politically biased movie making political points, nor is it a study in the devolution into civil war. We can all imagine many scenarios for how that could happen here. This is about what a 21st century American civil war would look like, how thin the veneer of "American solidarity" is, even neighborliness, how easily we can divide into factions and see each other as "other" and how in the middle of the chaos and racism and horror and opportunism and selfishness that comes with civil war are the press trying to capture what is happening in real time. How long can we supress trauma? Are some people just built for that work? What do you have to sacrifice as a human to do it and is it all worth it? Do we want to do through this as a "country"?
It's thought provoking, painful, and touching.
For those who want a very clearly laid out narrative of who did what to whom and why and all that led up to civil war, this isn't for you. There's no way to fully understand all the perspectives that would lead to a civil war, and too many countless scenarios in which it could happen, and good guys vs bad guys is trite and played out.
This is about something bigger.
