I personally love the show. Despite that fact that Sheldon comes across as rude and socially inept, he still is a successful, respected academic - an inspiration for Aspies everywhere. I particularly enjoy that Sheldon has been allowed to grow, and develop his relationship with Amy, again giving inspiration to young, perhaps depressed Aspies who might fear that they may never meet anyone. While the word Asperger's has never been uttered on the show, it still portrays the condition in a positive, if exaggerated light.
