This stunning horror film by famous short story writer M.R.James is only 40 minutes long but is probably the best horror film I've ever seen. It terrified me as a kid and stood up well when repeated recently, although it came across as a more playful piece this time around. Fast film stock gives a horribly verite atmosphere to the proceedings and nothing can beat the grotesque sight of the kids with long fingernails marching remorselessly towards the camera to the eerie sound of a Hurdy Gurdy. Respect due to a work of genius.
