For the Channel:
- Network Decay: As said on the main page, the channel has moved away from ACTUAL Nicktoons in favor of original programs and imports (like the Yu-Gi-Oh! franchise). They've even aired live-action programming, including Power Rangers and NickCom reruns.
For the series of Cartoons:
- Broken Base: Do KaBlam, Pelswick, Mr Meaty, and Wayside count as Nicktoons?
- Ensemble Darkhorse: Invader Zim, hands down.
- The Scrappy: Fanboy and Chum Chum and Breadwinners are not without fans, but are notoriously unpopular.
