Honorable Mentions

Gravity Falls
June 25, 2012 February 15, 2016 8.9/10 (8.8/10) "The absolute best of Disney Channel! Hands down! I really hope we haven't seen the last of Mable, Dipper, and Grunkle Stan. I say one more season."

8.4/10 (8.9/10) "I'm a massive fan of this show and I think it's easily among Nickelodeon's best cartoons of all time. Dark, comedic, and endlessly quotable characters. Absolute classic!"
Adventure Time
P12563770 b v8 aa
April 5, 2010 September 3, 2018 8.6/10 (8.1/10) "This began a cartoon renaissance and it definitely deserves a mention. It's purely a personal bias that made me choose Steven Universe instead."
Star vs. the Forces of Evil
P11178191 b v8 ab
March 30, 2015 May 19, 2019 8.2/10 (8.4/10) "Ok, as much as I adore this cartoon, I can't justify it as one of the best American cartoons. I want to, but I can't! I love the animation, the colors, the sounds, the voices, the whole cartoon just works in this perfect seamless harmony for me. It just presses all my buttons. Subjectively, I love it, but objectively, it's probably not among the best."
P206489 b v8 ae
September 13, 1993 November 14, 1998 7.9/10 (8.8/10) "If it had just been Yakko, Wakko, and Dot, and Pinky & the Brain, this probably would have been very close to Looney Tunes for be, but segments like Reader & Runt and Good Feathers were just okay to me. But the Animaniacs on their own were very nearly on this list."


  • The Simpsons and Looney Tunes will be reviewed again in Top 6 Cartoons That Got Bad since these two shows became much more bland as these shows went on (The Simpsons: 27 years; Looney Tunes: 87 years).
    • South Park will be an honorable mention on the same video, when he briefly talks about season 20.
