A comedian whose name I don’t remember once said that to people who would now be about 35-50, the phrase “Sooouuuuuuuuuul Train!” were still the most frustrating words on the planet, because it meant cartoons were over.
My ideal Saturday mornings would included (don’t care about what order):
KORG 70,000 BC (also my favorite lunchbox)
FLASH GORDON (the Filmation version)- one of my favorite cartoons ever (one of the few where living people [Hawkmen and others] got killed- loved their battle sequences)
The Tarzan Filmation- especially when the talking ape (“the Bol Mongani”, or something like) was on
And the last one I remember liking, even though I was a bit old for it, THUNDARR!
I loved the artwork of America in ruins (Neanderthal like hordes under the capitol dome, for instance)
I can think of lots I liked but not as much, lots I couldn’t care less about, but these were probably my Saturday morning dream-team.
