Most critics respond warmly to All of a Sudden, praising its hopeful treatment of care, friendship and human connection. Praise centres on Virginie Efira and Tao Okamoto, whose rapport gives the long conversations emotional weight. The reviews also credit Hamaguchi’s patient direction and attentive dialogue with making caregiving compelling drama. For its strongest supporters, the optimism feels earned through the tenderness of the performances.
The spread is wide, however, with the leisurely pace and three-hour runtime dividing opinion. The AV Club finds the length justified, while Deadline argues that excessive length and lecture-like passages weaken the emotional impact. The Guardian admires the quieter exchanges between caregivers and patients but finds the film overly precious and self-conscious. Even favourable reviews acknowledge moments of sentimentality or overly prescriptive thinking; the main disagreement is over how much these intrude on the relationships.
