Guy Lodge Film CriticNot since Alfred Hitchcock’s 1927 silent “The Ring” has there been a boxing film quite so quiet as “Small, Slow But Steady,” a gentle but hard-edged study of a flyweight female pugilist in suburban Tokyo. More concerned with the wear and tear of everyday life than pummeling sound and fury, director Shô Miyake’s measured, unsentimental adaptation of a memoir by Keiko Ogasawara — who turned professional despite the difficulties of lifelong deafness — turns out to be somewhat aptly described by its own title, though none of those adjectives quite conveys its rare and delicate grace.
