Based on a 2021 novel of the same name by Ryo Asai, the film looks at the impact that a fetish for spouting water has on the lives of two former classmates. Along the way, it delivers nuanced takes on the tolerance of difference, empty diversity gestures and social isolation. Titillation is notable for its absence. An unexpected turn in the denouement brings the sympathetically portrayed fetish into contact with undeniably abnormal desires, muddying the moral waters. (hollywoodreporter.com)
