It wasn't a flop,
But it did first try to attempt to reach the teenagers of the early 90's,
With shows such as ren and stimpy, are you afraid of the dark, hey dude, salute your shorts, Pete and pete, clarissa explains it all and of course round house,
All originally caters to teenagers and above, eventually younger kids still watched it, thus making more snick shows suited for kids rather than teenagers, rugrats, Doug, ahh real monsters and etc, I stopped watching nickelodeon around 96-97,
All that was barely decent in the first two seasons, but became wack and cheesy, I hated angry beavers, also the wild thronberrys and etc,
I guess if you were in the double digits in the 90's, nick/snick in its prime was 90-96, I also hated how rugeats got all technicolor on a brother, when dill came, they changed the animation of the show, they added to many colors, the sky should not have been 3 colors, I felt like I was on an acid trip, I liked the loose drawing approach the first few seasons rugeats had, I like to see the faults, that's hard work to me as an artist.
