Rain Man wasn’t even autistic IRL, nor was he intellectually disabled. He had a neurological condition, but it was extremely rare. Yet somehow, by making the fictionalized Rain Man autistic , autism was associated with being a savant, which is something totally different. Besides, megasavants like Kim Peek come along once in a generation, if that.
Bones, on the other hand, doesn’t even seem autistic to me. It’s like someone read a little bit about some of the outward manifestations of autism, misconstrued nearly all of them, and shoehorned them into one character who also still had to be likeable somehow.
Autism as cheap humor, such as Sheldon Cooper, rankles me a bit, but not quite as much as Autism As Plot Device. This is where a two dimensional autistic character is created to teach neurotypical characters a Very Special Lesson, or for them to demonstrate how strong or compassionate they are for allowing someone who’s just a tiny bit different from them to occupy the same physical space. Gag.
From what I’ve seen of Community, literally only a few episodes, I think they do a good job of creating an autistic character who isn’t a plot device or a cheap joke, but a character in the same level of all the others, so just happens to be autistic. Not sure what else qualifies. There are woefully few examples.
