Does Sheldon become worse in the latest seasons? He seemed like a very accurate, though funny representation of someone with Asperger’s in the few episodes I watched early on.
The problem is that - as far as I can tell - he’s never been officially declared Autistic, and any canonical mention of any form of Autism in relation to him has been derogatory and purely for laughs. Most of the “humor” the show now derives from his character is in getting the audience to go “oh wow, how do people put up with him? He’s awful”
(IF ANYONE IS AVOIDING THE DERELICT BLOG BECAUSE OF POTENTIAL SPOILERS, DON’T LOOK AT THESE. I mean the whole “it could be an AU and they might actually all die horribly” thing still applies, but yeah.)
