As a dad with an autistic teenager. it is a fabulous drama in families with this sort of problem. though I have watched just one episode of first series and too early to judge it( I've just discovered it). All my concentration goes to Joe and his behaviour and understanding of others around him. The conflict which is arouse after the shock and family members reaction to him and each other.
I will definitely get a better judgement by watching all parts but this one really affected me.
