Definitely agree. It was a dud of an episode. Remove the frequency of jokes and the script wouldn't be out of line within a Season 13/14 marriage crisis episode. That being said, that's not my signal for decline. I think I may have said it before, but earlier in the season,
Bart's Inner Child. If you remove the jokes, majority of which are fucking hilarious, it's probably one of the most structurally inconsistent episodes in the show. Earlier episodes of
The Simpsons. Felt connected through some kind of narrative.
Inner Child felt like a series of vignettes, although funny, feel very disjointed. Think about it: first act is the matress shit, second act is when Marge tries to get self-help and shit (which only starts because of a meta joke, one of very few episodes I can think of where the plot is inspired by a meta joke) and third act the whole town decides to be like Bart, only then reflecting the title of the episode into a plot. It's like George Meyer spent his whole time taking all the best jokes the writers wrote and making it into a loosely connected story with wacky gags. The episode itself really does kind of lack the grounded nature the show had. There's loads of visual and reference gags in this one, all of which are timed well and funny, but they lack. Plus, the third act.
I mean, you can go even earlier. Nobody mentions
Marge In Chains, a Season 4 episode that starts off fairly normal (although Apu is weird in this one) and throws a legendary second act pulled through by Lionel Hutz, but devolves into shit once Marge goes into women's prison. Normally with this, you'd think that the writers would put focus on the house falling apart without Marge, and they do, but they go to the extreme route, by suggesting that THE WHOLE TOWN would fall apart without Marge being the balance beam that holds things together, which is a really, really strange plot point. Hell, not to drag out my autism further, but you could even say
Marge Vs. The Monorail or
Mr. Plow marked a shift in the nature of the show due to celebrity overload and the absurdist humor within those two episodes being the forefront.

I don't personally agree that Season 5 is the weakest season of the Golden Age, but I could see why. A lot of the episodes in that season have wackier plot points, jokes, and bigger adventures rather than the small compact peaceful Simpsons nature. Surprisingly, I think Season 4 is the weakest, because I feel that Season 4 is very inconsistent with what it wanted to do. It started out fine, but by the second half of the season I feel like it kind of fell off. I think the last 4 episodes of Season 4 are some of the weakest of the Golden Age, mostly because they weren't that funny or they had a lot of story problems, and I think a lot of the favored Season 4 episodes are overrated as fuck...except for
Last Exit To Springfield. Season 6 is my favorite season of the show because I feel like it's a perfect balance. It's Season 3 and 5 in a blender. You take wackier jokes and put them with more grounded stories, and boom, Season 6. Perfecto mundo.
