In addition to watching the trailer, did you watch the Free pilot episode on ABC's on line link:

Since Minnie Driver is a well known actress, she's the "star attraction" for viewers. And while her role is prominent, I think the show is striving for an ensemble cast.
In the pilot episode, the story arcs around JJ's younger brother's angst, his desire to fit in, his need for his parents' attention (as a middle child), and validation of what he wants and needs as an awkward adolescent.
Every character participates in this episode to give us a better idea of their connections. Mom is running the show, because, well, in real life, Moms do run the show.

In the pilot, it's clear that all of her children accept that aspect of Mom, but aren't afraid to let Mom know that they need more or something different than what she's delivering. This allows us to see Mom digging deeper into how she can be the best Mom to all three of her children.
This is a story about a family, with a family member, who has CP and needs a "voice" to speak for him. That voice may be his brother, sister, Mom, Dad, or the janitor JJ hired. They don't put words in his mouth. They speak the words he writes/indicates. Based upon the pilot, I sense that JJ will be a core character, because of his interactions with the other characters.
I think “Speechless” has good possibilities, if done well, and I’m just thrilled and grateful to see a prime time show about a family with a disabled family member. That’s a modicum of progress.
Let’s watch it this season and discuss it here!
Love & Light,
