The early streaming numbers for the show should be good.
What will ultimately hurt this show is what hurt Our Kind of People.
This show might technically be breaking ground on major network tv, but multiple shows with soap opera elements have come and gone on cable tv. The scripted shows, and the "reality" shows.
The first set are free to use language and content without the constraints of network censors. The second set use real life people whose lifestyles the audience follows and copies.
The current shows have pushed boundaries to the point that it would be hard for Beyond the Gates to go lower than.
Wish them luck.
