Well, gotta be Buffy. It was at the tail end of the nineties and lasted into the naughties, but it counts imo.

It was just such a fun show for the era, and they managed to not only keep a consistent vibe, but turned out plenty of really intense shows despite the overall vibe being humor/action based

X-Files was a blast live… Not sure if it holds up to reality these days

matt frewer (max headroom!) in doctor, doctor

only a few seasons, they never really gave the show time to find its footings but frewer is fucking hilarious and i lament he has not done more comedy.

Star Trek: The Next Generation

Farscape

YuYu Hakusho.

Ed, Edd, and Eddy barely squeaks into the category of 90s shows but it’s one of the best. Cosmic horror, undeniable metaphysical nightmares beyond human comprehension, all with a thin coat of anti capitalist veneer just to make it shine out a bit (though the entire cartoon cartoon lineup had that as a central running theme).

90s Simpsons were the best.

Twin Peaks!

Red Dwarf! Smoke me a kipper I’ll be back for breakfast
