theres this really cool chart where you can see the overall IMDB ratings of peoples for every simpsons episode from season 1-34. you can also see where the quality starts to wane. the first 10 seasons are almost universally green, and it slowly becomes generally less well received after that.

the lowest rated episodes are:

season 23, episode 22
season 33, episode 1

Oh don't get that happy birthday Lisa song stuck in my head, you won't like the Hulk mad when you get him angry.

Yeah, that was a really bad episode. It wasn't long after that when the show became completely Flanderized.
Remember the episode when one of Marge's sisters came out of the closet, and tried to marry a female professional golf player that turned out to be a man who was pretending to be a woman so he could beat women at golf? Crazy times.

People say seasons 2-10 are the best, but I think the best is really like 3-7. 8 and 9 have some stinkers, and 10 is like 50-60% stinker.

second half 90s their episode were meh

Probably one from after I stopped watching in the late 10's. It had already been steadily getting worse for years at that point so it is likely that that trend continued and the worst episode came after that.

LISA IT'S YOUR BIRTHDAY
HAPPY BIRTHDAY LISA

i looked at the chart again and a few episodes in the first 10 seasons are low rated, which is interesting as they are considered the best seasons.

- season 6 episode 3 "another simpsons clip show". its a breather episode mostly comprised of clips from past episodes, so it is easy to see why it is low rated. such episodes usually existed to give the animators more time to work on new episodes.

- season 9 episode 2 "the principal and the pauper". this is the "principal skinner is a fraud" episode, and aye it is generally not well liked.

- season 9 episode 11 "reality bites" is actually the lowest rated episode of the first 10 seasons. marge becomes a realtor and works with lionel hutz (this is also the last time lionel hutz would speak in an episode, as phil hartman died 5 months later).

But honestly no one remembers because it probably happened after everyone stopped watching and it became a zombie franchise. I'm still not sure if its still running or not.

The one they made grandpa gay for no reason.

It’s easier to pick the one or two good ones.

Pretty much most of them.

All episodes that are not Treehouse of Horror episodes.

the treehouse of horror episodes are still great even in the new seasons. they are still disturbing and imaginative. even if peoples dislike the new seasons of the simpsons (which is fair, i do not like them much either) i will always recommend they still watch the new treehouse episodes.

The worst episode was when Matt Groenig made that underaged girl massage his gross gnarled feet all the way to Epstein's island.
