Eh, I've never actually sat and watched love, death and robots. But my understanding of it is it's a non serialized episodic program often revolving around a different sci-fi or fantasy storyline from episode to episode. Spiritually it's very in line with metal hurlant, or heavy metal in the US. But yeah unless there's heavy involvement from either of those magazines or anyone significant from the other productions. Calling it any sort of prequel or sequel is wildly disingenuous for sure.
Came here to say exactly that - this article is bullshit. I love LD&R, but aside from it being animated there's no similarity with HM. Some of the episodes are wildly different in theme, feel, and style. I don't see how anyone can call it a "spiritual successor" in good faith. Hell, as a diverse collection of stories and styles, it's hard to relate it to any one movie or show at all.
