Just for whatever this is worth to you, and I know you probably already know this, but networks rejected Breaking Bad, The Walking Dead, South Park, Mad Men, and, I think most infamously, Stranger Things.
There's nothing wrong with that --- perhaps the networks involved should have rejected those shows! You pick one, you gotta turn down another one. But having more venues specialized in a specific type of show means that, for instance, when BET passes on your thing, it can still find a home somewhere else.
I don't know anything about these particular shows. But look at the first couple episodes of Broad City --- not the extremely successful TV show, but the low budget web series that started it all. I'm inclined not to dismiss things based solely on production quality relative to what's on FX.
The rest of these points are probably well taken!
