We open day eight with Nicolas Winding Refn's Her Private Hell, a neo-giallo nightmare set in a futuristic city where a diamond-knuckled demon stalks young women in the fog. Half the audience walked out. We stayed. Pino Donaggio's score is extraordinary, the neon is relentless, and the plot is absolutely not the point. We talk about what Refn is and isn't doing here, and whether staying was worth it.
