The beguiling short-story feel of Paul Dano’s intimate family drama makes us share the experience of a teenager whose parents are ‘going through a rough patch’ that may break up the only security he’s known. The performances of Jake Gyllenhaal, Carey Mulligan and especially young Ed Oxenbould are low-key and high-intelligence; each seems a study of people we know, or people we might be. The observance of what rural America was like in 1960 Montana (or many places, even now) is acute. Highest recommendations. With Bill Camp; highest recommendations for this very satisfying piece of 21st Century moviemaking. On Blu-ray from The Criterion Collection.
