Those shows are definitely superior to Rick and Morty. But I still watch it just to turn my brain off sometimes since the show barely takes any thought to watch. Like south part or family guy. Or even robot chicken. It doesn't take a high IQ to understand pop culture references but they can be fun in their own way. Brock Samson is still one of my favorite characters because how ridiculous and over the top he is when killing people.
I agree that Rick and Morty is fun for what it is, but I don't like when people get extra credit for being mediocre.
I also don't like when people don't get the credit they deserve. I understand that John Kricfalusi is a pedophile and a scumbag, but there is an entire generation of people trying to rewrite history and pretend like his animation especially with Ren and Stimpy didn't change the game FOREVER.
You can see what you want, but other than the occasional Ralph Bakshi movie or Nelvana release, there was no adult animation to speak of before Ren and Stimpy. But because of the actions of its creator people want to rewrite history and act like it was never good or important to animation. I would argue that Ren and Stimpy and The Simpsons walked so that pretty much any other adult animated series could run.
And unlike The Simpsons, Ren and Stimpy fortunately happened the right way: it was only on for a couple of years before it got canceled, and then it had an r-rated limited run of a few episodes. The Simpsons should have ran until about 99, they should have stopped doing the show and then released like a trilogy of r-rated movies in the 2010s.
Sorry I always go into a rent when it comes to adult animation in North America because I knew it came down to three sources before the '90s: Nelvana, Bakshi and Kricfalusi. Erasing a third of that history because of controversy rewrites the legacy.
