Dude, you cannot judge a complete time period, every decade had Amazing and Abysmal animated content.
The early 90’s had Rocko’s Modern Life, Animaniacs and Rugrats... but it also had Bubsy
The mid 90’s had Batman the Animated Series, Dexter’s Lab, Hey Arnold!, Recess, Jonnhy Bravo, Angry Beavers, Pokemon (I know it’s an anime), Kablam, South Park but it also had Stressed Eric and Can in a Soup
The late 90’s and early 2000’s had countless good animated content but it also had APC, The Cramp Brothers and Eight Crazy Nights
And that goes with every era
