I'd go one more step and suggest the comic didn't leave them a lot to work with in the first place. They ran through the whole Night/Dawn/Day of the Dead arc instantly and firmly established that civilization was 100% gone with little hope of returning (which makes very little sense in that time frame). I can't blame the writers for not knowing what to do with that premise, other than having the supervillain of the season kidnap and torture people. I checked out halfway through the governor arc... not surprised they're still doing the same dance, just that it still hasn't ended.AMC unquestionably did Darabont and the show dirty, but I think people are being a bit when they insist that the first season was perfect and the rot only started to set in when Darabont got ousted.
So they upgraded the subtext to the text? They followed woke casting rules to a T:I was really into it for the first four seasons, but then it started getting really preachy and obnoxious. I'm not one to constantly complain about "muh SJW themes" every time a black person farts onscreen, but it felt like they were trying way too hard, and episodes would be brought to a screeching halt so a character could rant about sexism or the issues trans people face in prison.
1) Blacks/latinas are the elite: jokes revolve around how competent/intelligent they are
2) Latin males and Jews are in the middle: they have negative/quirky traits but are decent, sympathetic
3) The two stupid cops that everyone hates and all the bad guys are white
Most network programming I get second-hand exposure to has shades of this, but I thought Brooklyn 99 was one of the less-subtle examples.
