For anyone who has an autistic family member, is an autistic family member, or knows an autistic family member, this is a heart warming depiction of the struggles often faced and a validating representation.
For everyone else, autism is not "intentional" behavior. The father is not just angry, he is dysregulated. The son is not just disruptive, he is dysregulated. The grandfather is not just fearful, he is dysregulated.
Educate yourself and support the freedom for all people to be angry, disruptive, scared, and still accepted as valid human experiences.
