I watched it, then dd watched it who is autistic (high functioning) and she loved it, she did some of the portrayed things and does have a good understanding of how hard she can be to live with.
I always say, we got lucky - at four we did have a barely verbal (mostly screams) kid whose specialist told us she may never speak and could be ld, she did learn that year, and we discovered she could read already. But our friends at her school (for autism in the USA) weren't lucky and their kids did have chromosomal deletions, one is no longer with us (Retts). Autism is often the early symptom of something else, or they have both.
