It's hard for me to write a review with a lot of details because I am also disabled and it takes me a lot of time and energy to do so. That being said, it is not hard for me to sympathize with the struggle Yuma is facing, because I, myself, have to go through a similar experience.
This movie is the definition of why I love Japanese cinema - Their movies are about people, people who actually exist in the real world and no one is talking about them. Families that the majority of us would never get to experience their story otherwise or through another culture.
This movie is about real life, and how a person with disabilities slowly starts to become independent and be a part of the outside world. Obviously, it's not easy for these people, and it's certainly not something they can do by themselves, but the last thing anyone wants in this life is to be treated like a stranger and to be reminded of their "weaknesses".
Disabled people might not have the physical capabilities of a non-disabled person, and they definitely need some support and physical assistance, but apart from that, they're just like everyone else - they need friends, relationships, jobs, education, self-esteem, confidence and most importantly, to be treated like a normal human being. This movie addresses all of that perfectly and I would love to see more like this.
