Thought provoking, reflective, showing both the best and worst sides of humanity, stretching the characters across dimensions rather than compressing them into composites.
A world has collapsed, but not completely, the supply centres have been thwarted. A slow film for those requiring car chases and big bangs, this offers none, just the day to day struggle of a social world that has stopped rather than been obliterated. So no mad max stunts, or lord of the flies manhunts, other elements of both are gently integrated rather than obviously built upon.
Reminds me of the Survivors series of 1970's Britain, as we are led into the woods and barren fields of the countryside, as elements of the french round up emerge, along with paranoia.
The ending becomes another question, but given that Haneke asks deep psychological questions rather than states the obvious, the film has to be worked out to individual taste rather than the viewer being forced fed rusks to help with a smooth diet. This way the film lingers rather than evapourates.
