A great film. Woefully cheap. Blissfully purposeful. Knows exactly what it thinks and says it with brutal clarity and biting humour, all shot in a ragged verité style that seems strangely contemporary. A factory worker goes off his trolley, throws society's rulebook out of the window and reverts to being a caveman. And that's about it - talk about a high concept! There's no dialogue, only gibberish and grunts, but, incredibly, it works. It's easy not to like this film, but hard not to be impressed by it. Check it out for yourself and see.
