I loved Rugrats and thought Aaaahhhh Real Monsters was alright.
I probably liked every cartoon until I was about 9 or 10 and discovered Catdog which I hated for some reason. Also agree with Rocket Power, Disney's Doug, and Ed, Edd, N Eddy. I guess I can add Pokemon. When I was in 5th grade, that shit was a craze and I watch the cartoons and thought "The hell is this shit?"
