This meditative examination of the impact of the Vietnam war through the eyes of three sons - of a family who left (as refugees), a family who stayed and a father who invaded (US soldier) - and the scars it left on all, has a big heart. But despite its measured (and very slow) approach, it makes these three points a little too awkwardly (via blunt expositiry dialogue) for it to work as a seemless whole. But the visuals and the acting are high calibre.
