I have no problem with showing that life goes on with and around autism. We all know it does, and that it is a juggling act. All well and good.
The lazy stereotyping of the parents as hopeless, selfish, bullies with little empathy or understanding of anything, much less any insight at all into the child they have loved and cared for for five years, is beyond infuriating.
The cheap thrills with all the emphasis on sex - would typical family life and drama not be enough?
The easy get out of Joe behaving 'badly' at his sister's play - why was he there anyway? They clearly had no problem getting a sitter, as she was there with him. Since when would any family drag a 5 year old along to a showing of Antigone?! Let alone one who had little interest in being there, or ability to follow any of it. And having taken him, why insist on him removing the one thing guaranteed to keep him quiet and happy? Totally unrealistic, but could have been so accurate.
The behaviours shown were very good, on the other hand, and the scriptwriters/director seem to have ensured a lot of incidental parts of autism - lots of repetitive behaviours, many recognisable situations and outcomes.
