>>99802786>To me Simpsons ended in S9 with Principal and the Pauper.PatP may have been the beginning of the end, but the rest of Season 9 still had a LOT of solid episodes in it:
The City of New York vs Homer Simpson
The Cartridge Family
Reality Bites
Miracle on Evergreen Terrace
The Joy of Sect
Das Bus
Lisa the Simpson
Lost Our Lisa
Natural Born Kissers
Where the decline in quality becomes suddenly and sharply noticeable is in Season 10 after When You Dish Upon A Star. After that the show very quickly became centered entirely around celebrity cameos and wacky "what if The Simpsons parodied popular thing?" episodes.
