Barry Levitt from The Daily Beast described the film as "a tantalizing portrait of a filmmaker often at war with himself, a man with an undying love for the environment around him mired in increasing despair at the state of the world", and wrote that "even those who've seen every Miyazaki film many times will find exciting new insights here." La Croix Stephane Dreyfus referred to the film as "a well-conducted documentary, rich in archives and enlightening interviews". Téléramafilm criticCécileMury wrote: "this rich and beautiful documentary by Léo Favier invites us to rediscover him in depth: an intelligent tribute, gracefully weaving together the threads of biography and analysis of a work".
