What went on up there? Poppers and weird sex!
Very true. South park and Family Guy to name a couple.
Also, my theory is that the real world was starting to become more absurd than the show, especially with the internet, the Bush era, etc. These other shows were going for more raunchy jokes and the Simpsons kinda had to stay in the box they created for themselves. No sex jokes and the only real violent episodes were the Halloween specials.
Also, at some point they focused more on the jokes than storylines for episodes. In other words, it's almost like they started to write jokes and then created a weak storyline around it rather than the opposite.
You got it 100%. That's exactly what happened.
You know how The Simpsons' crew and Family Guy's crew were feuding for a while? That's because the Simpsons writers were jealous. They felt like FOX was grooming Family Guy to take over as the #1 adult cartoon, and FG was capable of going places that The Simpsons couldn't. One day, Matt Groening's son came home from school and told him that all of his friends thought Family Guy was better.
And over time, they definitely stopped caring about writing stories based around the characters. Every character turned into a parody of themselves. Bart used to be one of the best characters, but they don't know what to do with him anymore.
They’re not nearly as dominant as they used to be but they still have tons of bangers to this day. That episode “Barthood” was great. They won a best animated program Emmy in 2019
wild ass stat: Dan castellaneta was 29’when he started voicing homer. He’s 63 years old now, and the show is still not close to ending
I've definitely seen a couple good episodes lately. The Netflix parody two-parter like @Deltron mentioned, and the episode where Grampa got scammed out of $10,000. Homer got upset because he was supposed to inherit that money.
Before that, there was the Cincinnati episode, and also the Halloween episode that wasn't a Treehouse of Horror episode. But I think my favorite episode from the later years is the one where Bart takes everybody on a vacation and he doesn't want it to end because of how boring his life is.
