I had mixed feelings about that movie. I enjoyed it, but at the same time I thought that in 'Adam' it was as if they were trying to squeeze an example of every AS characteristic into one character in the short amount of time allotted by the movie, and in doing so, the whole thing ended up less realistic..
That's one reason why I liked "Mozart and the Whale". They seemed to do a good job of showing just how varied ASD can be amongst a group of people, with even the two stars of the film sometimes at odds with each other over their own respective traits and behaviors.
