Hate anime and furry art, but the art style that stands out to me as my most hated is what my wife calls "Kim Possible style". Don't know how to describe it, but basically the art style for Mark if the Ninja. That game is essentially perfect to me, but fuck do I absolutely hate that art. Everyone's got identical square chins and looks like a Cartoon Network character circa 2003. Fucking despise it.
I also hate the poppy, overly colorful, extremely upbeat, super positive, woke type art that's so prevalent in indie games today. Hard to describe what I mean, but just check out Coffee Talk for a perfect example of what I'm talking about. It's like Western weeb shit. Fucking despise it.
