This is actually a good thing. Apparently we live in a cord-cutting world where network TV should be able to at least compete and yet all they want to give you are reboots, warmed over old stuff and procedurals. The comedies all follow a formula. Something happens, we fix it. Diversity (of ideas and how to present a story) is not encouraged at all.
They do "comedies" like Black-ish, but are totally devoid of humor and are supposed to be considered good because "yeah, well that's some real ish." I would kill for this generation's Seinfeld or a Married w/ Children with that type of sharp writing, but the networks are afraid even as their ratings go into the toilet.
The only question I have is, if the ratings no longer matter, why does it matter if the writer's have big names? No one is watching these shows for the writer's names. They are watching them for the ideas, characters and storylines. Morris Chestnut just got on a show that is basically the Blacklist but with the genders reversed. Good grief.
