i mean i thought he was shootin for y'know
anime
but but, honestly american animation is just as good
except for fucking family guy, are you kidding me, what
lets start a list like this, you had some decent ones, and this list is about GOOD and VISUALLY appealing ANIMATION. humor may be involved, but what we are focusing on is eye candy
Super Jail (if you like batshit crazy cell animation, this is for you)
King Star King (the pilot, however a full season is on its way. this is from the genius mind of JJ Villard, he also pitched some other amazing shows and is responsible for an amazing short called, Son of Satan)
The Marvelous Adventures of Flap Jack (from the mind of Thurop Van Orman, hes also working on a full length claymation and is also working on Adventure Time and Regular Show)
Samurai Jack (from the creators of Dexter's Lab, all the more reason to watch)
Ed Edd and Eddy (fucking super funny, they use the squiggly line animation to make things seem more life like, similar to what Home Movies did in the first season. Aside from the animation, the sound design is by far the fucking best I've ever seen in a cartoon.)
Ren and Stimpy (pretty much grew up on it, the shit is bonkers however I'd advise staying away from the "adult" version, its garbage.)
Mission Hill (good, smart humor. the cell animation is traditionally inked and the color pallets is extremely eye catching. probably one of my favorites that I caught on Adult Swim, its too bad to be canceled)
i'll add more, but i wanna do stuff and not type right now
