Let's see how easy it is to talk you out of seeing A Field in England. First of all, it's in black and white. Second, it takes place in the 17th century, and all the characters speak in impenetrable dialect while being covered in varying degrees of filth and shit. Finally, it's a self-consciously arty, virtually plotless exercise that's capped by a bug-nuts trip-out sequence in which one of the characters shovels handfuls of psilocybin mushrooms into his mouth like they're Girl Scout Cookies. Now let me try something harder: persuading you that A Field in England—the fourth feature from English director Ben Wheatley (Kill List, Sightseers)—is not merely worthwhile, it's among the most challenging and astonishing pieces of cinema around, transcending any "drug movie" clichés in favor of something fascinating, terrifying, and unique.
