Almost all major shows have to be cast with the main players as most beautiful people who are better than the rest of us in bravery, morality, intelligence.
Oh, and it's rare to see a disabled person even guest star on a show let alone be a lead part.
Every episode has deepened the roles for disabled characters, and while the rest of TV generally keeps the disabled in the closet, this show has them out just being real.
