What a brave and exciting film directed by the Japanese director Ryusuke Hamaguchi. Soudain, which premiered this Friday in the official competition of the Cannes Film Festival, has the audacity to take all the time and words it needs to reflect on a topic as uncinematic as care for people with neurological diseases, and it does so through a beautiful story of friendship between two women, the director of a nursing home in Paris who introduces a new humanitarian philosophy in the center (Virginie Efira) and a Japanese theater director with terminal breast cancer (Tao Okamoto).
