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.
- Snark Bait: The channel became notoriously mocked by fans due to the aforementioned Network Decay but also because it's been noted that whenever a Nick cartoon is not doing well (whether it's not popular or it's not in the same level as its two juggernauts), it's thrown into the Nicktoons channel and let it quietly fade away.
For the series of Cartoons:
- Broken Base: Do KaBlam, The Brothers Flub, Pelswick, Mr. Meaty, and Wayside count as Nicktoons? While none of them were produced by the Nickelodeon Animation Studio in California, KaBlam! was the only one actually produced by Nickelodeon via their live action department (despite being animated). It was referred to as a Nicktoon on-and-off by the company all through the '90s and into the 2000s; 2016 had them refer to it as a Nicktoon again. The other four were all referred to as Nicktoons when airing on the channel until they lost each show's airing rights, even then someone working at NickSplat attempted to refer to Pelswick as a Nicktoon and advertised the show to air in early October 2016; it was replaced with The Wild Thornberrys. Out of all the shows listed, there seems to be the most debate on whether or not Pelswick is an official Nicktoon.
- Contested Sequel: CatDog, The Brothers Flub, Pelswick, ChalkZone, The X's, Wayside, Back at the Barnyard, The Mighty B!, T.U.F.F. Puppy, Robot and Monster, Sanjay and Craig, Pig Goat Banana Cricket, and Bunsen Is a Beast are the major ones. Some like The Angry Beavers, Catscratch, Harvey Beaks, and The Loud House are much less contested, but still broke the base.
- Ensemble Darkhorse: Invader Zim, hands down.
- The Scrappy: Fanboy and Chum Chum and Breadwinners are not without fans, but are notoriously unpopular.
