Very interesting and surrealistic movie. I've actually felt dread for a few days after watching it (especially in light of recent events in america). Seeing the grounded reality of open warfare in a first-world country and its impact on human psychology is a pretty eye-opening experience.
I mean we have seen a lot of movies showing bombastic action war pieces set in the US, but nothing as grounded and psychological as this, from what I recall at least.
Might not be a film for everyone, but sure is worth checking out if interested.
