Down to Salisbury yesterday evening to see this beautiful film. The plot is excellently summarised in the Wikipedia entry here. Individually, the elements of the film - Captain Vidal the fascist officer, the mystic fairytale scenes - could easily have come across as stereotypes. But the director has crafted it so that they carefully interlock and convey rightness and a deeper reality.
Yes, there were (and are) people just like that; yes, sometimes we do withdraw into our inner world, dealing with the unbearable through the construction of a parallel narrative of myth and archetype.
NOTE: I thought there was a lot of CGI (computer-generated imagery) in this, but it turns out the faun, and the 'pale man' monster were both a heavily made-up Doug Jones. I don't think the fairies were real, though ...
