this is an interesting topic. I think the best autismo characters are bound to be the ones that were written accidentally, based on someone the writer knew (or on themselves) without realizing it was autism, thus making them less archetypal and more realistic and dynamic. I don't care about any of the characters she named but the comments had 2 good ones, Abby from NCIS and Bones from... Bones. Coincidentally those were two of my favorite characters back when I watched a lot of TV as a teen. Bones in particular had some really blatant symptoms of autism, they were core traits of her character and often played to comic effect, but there was never any explicit mention of autism in the show AFAIK
