I thought sci-fi dystopian action with maybe a dash of socio-political messaging.
It became clear rather quickly that there was a bucketload more than a dash. It bears much resemblance to Brazilin a way. The settings claustrophobic and implausible quite intentionally. Do make sure to watch subtitled, or you'll miss out. Don't go relying on that faulty translation gizmo. It's hard to hear, and often incorrect.
