Wasn’t truly into this until the last twenty minutes, where it suddenly roared into life and ended up fully owning its ghoulish, yet deeply affecting, central metaphor. Obviously it’s not ideal to have to wade through an hour of repetitive ‘bumps in the night’ before the movie gets where it’s going - and visually it’s so dark large swathes played more like an audio drama - but the finale really does feel worth the wait.

Traverses much of the same emotional ground as Thunder Road, but in a more scatty, less satisfying way. It has its moments, but overall I was disappointed.

If you’re looking to get angry - and I mean blood-boilingly, ear-steamingly furious - then I’ve got just the documentary for you...
