SlackerCats - obscure, ran for half a season

Clerks The Animated Series - obscure, ran for half a season

Carol and the end of the world (Mainstream but wildly serene, surreal, and overtly human)

Moral Oral - pretty dark adult show

Ren and Stimpy - pretty dark for a kids show

I’m sure I’ll think of a few more

I’m surprised Ren and Stimpy made it in the obscure list. They were about as popular as anything when they were on.

The co-creator died a couple days ago
