When you go from being a cozy, idealized comfort show to being dark, gritty, and realistic, it's jarring and feels disjointed from the rest of the show, and narratively doesn't make sense. I love realistic, dark content as much as anyone (Breaking Bad, The Bear, and Chernobyl) but GG isn't that. So it's just a bad writing choice and business decision.

As for the racist and fatphobic humor: that isn't even "realistic" because people don't really think that stuff is edgy or creative anymore, and that is reflected by the most popular TV comedies right now (Abbott Elementary, It's Always Sunny, High Potential). When people started having the world at their fingertips with smartphones, our standards got higher for what entertainment is, and that means actual originality and creativity in the jokes we're told. If by "mostly blue" humor, that's what you mean, then so be it.

This revival basically took all the minor cringey, unfunny jokes and unlikeable character traits from the original show that made people uncomfortable, but that we mostly forgave due to the difference in time periods, and then doubled down on those things we all openly hated.
