The shows artstyle embraces being inconsistent, flat-like, and cheap looking cause that’s the way the Japanese view western cartoons, tons of anime series are more realistically proportioned and on-model so that’s basically the Japanese standard for animation. Also helping is the fact that the show was released around the time when most western cartoons used that thickline UPA-inspired artstyle, it’s particularly The PowerPuff Girls that stylistically influenced it the most.

The writing helps too, influenced by shows like South Park and Drawn Together, the shows riddled with vulgar humor and raunchiness cause adult animation in Japan could tend to be more "mature" in most cases, they’re aware that most adult animated western cartoons on the other hand embrace being as adult as possible by being riddled with swearing, violence, and sex jokes. Theres also tons of pop culture references since that’s a standard form of comedy in western adult animation, though it seems like the show isn’t really that aware of how to replicate the satirical element of them so that part just boils down to more pop culture references.

The fact that the show is apparently hated in Japan but loved in America is funny to me. Like you don’t see the Japanese liking anime-inspired western cartoons like Avatar or The Boondocks, the only western cartoons they care about are ones that actually look western.
