'A Field in England' is exactly the film it tells you it's going to be: set entirely within said field, it tells the story of a group of soldiers from the English Civil War going mad from a combination of (the 17th century version of) shell-shock, their own religious beliefs, and an unhealthy dose of magic mushrooms. It's brilliantly acted, imaginatively shot and scripted, and yet, having watched it, I find it very hard to say what it's actually about. Stylistically, and atmospherically, it's coherent; yet its artistic success is, apparently intentionally, not supported by logic. I think it does what it sets out to do; but what exactly that is, it's harder to say.
