“Fantastic Fungi,” an award-winning documentary on Netflix, sheds light on the fantastic workings of these strange organisms. …The film, directed by Louie Schwartzberg and narrated by Brie Larson, dives into this unusual and still mysterious world. It also follows mycologist Paul Stamets, known for his rousing speeches on fungi and his contributions to scientific research on psilocybin, a chemical compound produced by a few hundred species of fungi. …“Fantastic Fungi” spends plenty of time on the potential of seemingly magic mushrooms, and can wax a bit too aggressively about fungi’s future. But overall, the film is less about psychedelia or natural medicine than it is about connections — of fungi, organisms, humans, planet. Its stunning visuals underscore the message. …The film’s tone of hope and wonder matches the blooming beings.
