Nadie sabe

" Poesía del desamparo. (...) una obra maestra sobre el placer y la angustia de vivir (...) es una de esas películas en las que cuanto peor lo pasa el espectador, silencioso sufridor ante lo que está viendo, más fascinado se siente. Por su poesía, por su delicadeza, por su maestría "

— Javier Ocaña de El País

"En este ejemplar relato sobre la pérdida de la inocencia la sociedad no es insolidaria, simplemente no existe. Kore-eda narra cómo cuatro náufragos intentan sobrevivir en una isla desierta después de ser expulsados del País de Nunca Jamás, y lo hace controlando con mano maestra el uso dramático del espacio cerrado, aniquilando cualquier rastro de sentimentalismo fácil y respetando el punto de vista de sus protagonistas, desconcertados vagabundos que se ven obligados a construir un mundo propio con fecha de caducidad. Es difícil encontrar una película sobre la infancia tan poco condescendiente con sus criaturas y tan sabia al describir su desamparo."

" La naturalidad aplastante de los precoces actores llena de fuerza las imágenes elegantes y realistas de este filme "

— Alberto Bermejo de El Mundo

"Their tale is a rich, awful congeries of primal and distinctly modern fears, from the universal childhood fantasy of parental abandonment to the more grown-up suspicion that big cities are places of cruel isolation and indifference. Mr. Kore-eda explores nearly every emotional nuance and implication of the story, without for an instant succumbing to sensationalism or melodrama. The content of "Nobody Knows," which should consolidate his reputation as one of Japan's most interesting and original filmmakers, is inherently upsetting, and watching the film is, to some extent, a punishing immersion in impotent dread."

"Rejecting the socio-realistic, grungy approach such subject matter would have received from most Western directors, Kore-eda sketches the inner, spiritual and emotional lives of the children with subtlety and sensitivity. (...) Though the film is bolted to the real world by many practical details of day-to-day life (food, money, clothing), and during the first hour is lensed in a realistic way, Kore-eda imperceptibly creates a world which is increasingly bordered by just the kids' emotional horizons. As order and cleanliness start to break down inside the apartment, the film's visual style actually becomes more, rather than less, rigorous; and the whole movie, which seemed to be going nowhere, gradually takes on a shape and sense of purpose. As a casual tragedy reshuffles the kids' lives, the final reels deliver with a quiet power."
