Most of adult swim is trash. Metalocalypse is definitely better than average but squidbillies is slop, so is a lot of stuff people here might claim to like including and especially robot chicken.
squidbillies, i think, is a good example of something that appears on the surface to be completely stupid, but actually has a pretty clever core. South Park is kind of similar, I think I'd have a difficult time convincing my parents generation, for example, that South Park is at times one of the smartest shows on TV.
Squidbillies is more clever than you’ll ever understand. Definitely not “slop”.
From your comment it is very clear you don’t enjoy irreverent humor or animation really. Not everyone has $200 million to blow on Tron: Ares level animation.
I liked Moral Oral, and the PJs, Venture Brothers, and even really whacky stuff they did like
Xavier: Renegade Angel. I could even sort of get stuff like Superjail. But Squidbillies is a bridge too far. So was home movies.
