Autism ahead.
-I don't really watch cartoons and haven't for awhile. Even older ones from my childhood I can't get myself to watch often because of my rackets on adulthood.
-That said, I still firmly believe Grim Adventures of Billy and Mandy is one of the more brilliant cartoons made in the 21st century and I'd say it tops just about anything right now.
-Invader Zim was never good. It had its moments but most of the time it was loud and cringey. It also groomed the MySpace wave of lolrandom retards and I firmly believe this is part of why internet culture from 2007-2010 was so fucking awful.
-While I never watched it religiously, I liked the early seasons of Adventure Time and if my younger brother was watching it I'd probably sit down with him. At first it felt like a D&D show, because anyone who's played an actual game of D&D knows it usually turns out like what you saw on AT. Once it started getting too shippy, I stopped caring.
-A vast majority of Disney songs are either unmemorable or totally lame, pollyanna nonsense. Two notable exceptions are "Bells of Notre Dame" and "Hellfire", which coincidentally come from the same movie.
-Speaking of Hunchback of Notre Dame, while it's got great personality it's also not that good. Barring the beginning and the religious themes it's just the same kind of saccharine "always be yourself!" and "don't judge others!" nonsense you get in most children's media since the 90s.
-Building on that I wish we could move past this "oh my god [X Movie] is so dark and adult it's really not for children!" mindset we get whenever a movie shows kids something a little darker. Bullshit. Hunchback is fine for kids and unless that kid is a pussy and/or autistic they'll have no trouble handling it. Children are resilient. Empire Strikes Back is beloved by kids of all ages and it's significantly darker than any Disney film.
-Treasure Planet is only okay, not the hidden gem people like to say it is. It's got good art style and music and the Long John Silver re-imagining was pretty cool but I think people grossly overstate its quality. It also had furries, which is bad. Fight me.
