There is a lot of good about this film. It is breathtakingly beautiful. For Western audiences, it opens windows into Shinto practice, Japanese superstition, and--of course--the magic of the ryokan. But--and I do recognize that I am bringing my Western perspective to this--I found the film's cultural insistence on Okko's forgiveness fairly upsetting.
I've seen the film and its manga marketed as helping children cope with loss. I think it MAY be helpful for this purpose if plenty of context is given. Trauma is a complicated and multi-dimensional and personal thing, and healing from it must be led from within by survivors themselves.
Okko's emotional distance from her trauma throughout the majority of the film, including the ways she copes with or even ignores it, makes the sweeping climax of the movie--her readiness to forgive and serve someone who has wronged her deeply--fairly unbelievable. The film strongly suggests that had Okko decided she wasn't ready to forgive, everybody around her, not to mention the culture of her resort world personified by her frenemy Frilly Pink, may have understood why, but would have been deeply disappointed in her.
I want every trauma survivor to know that forgiveness should always be on their own terms, no matter what friends, family, or culture dictate. People who are healing don't deserve to have the weight of others' disappointment on their shoulders. I can only reservedly recommend this film.
