First off, Matt Groening has no involvement with Bob's Burgers (though I can see why you would assume that, Bob's Burgers has a similar style to the Simpsons).
Second, it's just that adult cartoons take so much from Simpsons, South Park, and Family Guy, all of them feel so interchangeable with their style of humor. Heck the recent Bordertown cartoon is just another carbon copy of other cartoons Fox has been releasing. I'll admit, I'm not the biggest Simpsons fan out there because I grew up watching other cartoons, but I fear Matt Groening's style will rub off in this new cartoon, and if it's any good, then fine it's good. But honestly, I wish more cartoons aimed at older audiences would take a page from more recent cartoons like Steven Universe and MLP. I think the world of animation could be a better vehicle for storytelling, not just sitcoms or irreverent comedies, but much more broader and diverse genres.
I just want cartoons to tell really good stories without the need to be a contest of who stuff as many irrelevant pop culture references as much as possible or how can my cast be as two-dimensional as possible.
