Part sweet romance, part mesmerizing art film, “Syndromes” was inspired by Weerasethakul’s childhood memories and the love story of his own parents, both country doctors. Nearly unclassifiable, but gentle and unassuming as the verdant Thai countryside and breezy outdoor parks where much of the action is set, the film’s true-to-life rhythms will draw you in, rewarding your patience with a few breathtaking moments (a solar eclipse, a rasping air duct) loaded with symbolism. Dissecting what it all means isn’t really necessary. Just let this film’s naturalism and easy humor envelop you, and you’ll leave with an exhilarating sense of refreshment — and perhaps, even spiritual edification.
