It's really good if one hasn't done a ton of research into Autism (& Asperger's). I'd call it repetitive in its presentation, but that's rather common in documentaries, lectures, presentations, etc nowadays. The descriptions of atypical development (delay, deviation, & dissociation) were the most interesting part for me, but the focus is very much on delays (& how global they are) & not the hyper- (early) end.
The genetics portion is bare-bones feeling, but that's because the research just isn't there yet. It's much further than it was, so the descriptions of the types of tests available & the (very few) things they've discovered genetically are newer. I think the more we learn about the genetics, the more likely the spectrum will become specifically divided into domains or such.
Afterwards, I was left with a very strong personal feeling that Asperger's needs to come back as a diagnosis. The more they went over the modern definitions versus the older classifications, the more alien I felt.
