I went on youtube and watched it, and i thought it was pretty good! I don't claim to be an expert or anything, but from what i've studied about AS they both seem a bit exaggerated... But that might have been just to highlight their difficulties. At least they both had symptoms that kind of appeared differently from one-another, instead of them both completely being walking stereotypes with no individual qualities. I could relate a lot to some of the little quirks they both had, though. They both had lots of animals(Donald had all those birds!), and i have a bunch of reptiles(that i talk to often!) and i love animals. I also like to mock animal noises and stuff like Isabelle was doing in that one part. Then, just the way Donald kind of seemed when he got nervous, shifting his weight from side to side, fiddling with his keys, is exactly the way i act when i get frustrated or nervous. So, yeah, all in all i thought it was a cool movie i could relate to Except for the being in a relationship part
