Very good reminded me of the feel of a Zombie movie i.e Dawn of the dead hybridised with a road film. I disagree with a lot of reviewers talking about it being apolitical. The politics is subtle and it is not a smack you around the chops polemic. You have to manoeuvre your own way through the narrative, there are pointers and if you fail to spot them more fool you.
One of the best soundtracks of any recent film with two cuts by duo Suicide. Not for the squeamish.
