Initially the clash of classes seems a little schematic. The straightforward Yudai sees a big payoff from the hospital, while Ryota adopts an arguably fake-noble stance with his insistence that the money doesn’t matter, that they have to come up with a plan for what’s best for the kids. Obviously a swap has to be made, eventually. But is that conclusion really so obvious? In a series of beautifully calibrated scenes, Koreeda explores not just the nature of parental love but of filial love, and as the painful alienated past of Ryota comes to light, his stiffness and lack of empathy become more comprehensible but no less kind of infuriating.
It’s a testimony to Fukuyama’s acting skills that as pig-headedly alienating as the character can be, he never becomes a complete turn-off. That’s also a testimony to the way Koreeda presents the situation; while the perspective is never not clear-headed, the abject heartbreak of the scenario is ever present. (Imagine the way that a typical Hollywood film about this story would make a deliberate burlesque of it.)
