>>974366353. Chris Parnell refused to come back for a full season because he disliked that Jerry was a cuck who everyone picks on, just like Cyrill from Archer. Rather than cave to his demands, they should have fucking retooled Jerry to make him less like Cyrill and keep Parnell around. The whole "Jerry is a super-predator" shit would have worked if they had committed to it full-on in season three and not broken up the marriage. They could have gotten some decent mileage out of Rick getting repeatedly foiled by Jerry; so that when he DID finally get one over on Jerry, it would have meant something.
4. The new writing staff. Granted, they were willing to call out Rick on his shit but they kept pushing the toxic feminist angle with the show. They could have gotten mileage out of Beth chosing Jerry over Rick at the start of the season and have her get her shit together AND forcing Rick to own up to being an asshole to her, which would have far better outlet for both pushing feminism and making Rick look like shit.
5. Toning down Rick's sociopathy. Season three's premier and the end speech, did more damage to the show than anything else. And stuff like Rick killing the not-GOTG and Rick tampering with Morty's memories for his own selfish benefit, just adds to the misery porn of Rick being unlikeable even by the standards of TV:MA shows.
