I didn't say anything about 80s cartoons. They were/are bad. The only thing they had going for them was, in many cases, great animators (often japanese houses), and cool space ship/robot ---steaming pile of meadow muffin---. GI Joe was one of the worst, because everybody got shot and no one really even got injured. Robotech was the only great one in that respect, as there were unabashed adult themes, and people died by the truck load - which in a war they ---smurfing--- can and often do.
A lot of that ---steaming pile of meadow muffin--- in the 70s, like Captain Caveman, was definitely HB milking the Scooby-Doo franchise. As with many other 60s stuff, the original SD was best, story and animation-wise.
Ren and Stimpy was mostly funny, but any of the other similar ones I didn't dig. ---fudgesicle---, I was in my early 20s by that time, anyways.
Simpsons was good, yes - I was still a teen then - but got more and more mainstream as years went on.
A pretty decent Saturday morning cartoon from the 90s that comes to mind is The Tick.
