My sister, who is visually impaired, and I have enjoyed watching the show and discussing it. (She lives in another state) That changed this past week when in one episode the hearing impaired son and his father signed to each other. Silence. This made it impossible for my sister to know what was going on. She does see shapes but does not see letters. For hearing impaired there is CC. But this is very insensitive for those that do not see well or see at all. My heart ached for her when we talked because she got very discouraged. End of show for her.
