The opening 40 minutes is perhaps the best short film ever made - amazing practical camera effects, fantastic acting, and an immediately gripping plot.
The rest of the movie loses its way and becomes a real slog of speeches and dark, drab shots. Yes, the ending that everyone hates is very hateable, but I’d already started doing the dishes and half-watching by that point so I wasn’t very bothered by it.
But who cares about those flaws when the first half is so astonishing? I sure don’t.
