Hehe, what a fantastic story! It reminds me of The Cabin in the Woods, except that might have been nowhere near as successful (or… wasn’t it?), and others such as Addams Family and Bewitched that changed the course of television forever. I remember when I first watched Night of the Living Dead, multiple decades after it was released, and was just shocked - shocked I tell you, shocked! - that it broke the rules of always ensuring a happy ending. Somewhere along the way I also discovered anime e.g. Fullmetal Alchemist, which in some version or another (JP? EN sub or dub?) opened up with one of the very first scenes being the image of his dead mother crawling around after her corpse had been resurrected and everything was bloody from his limbs having been removed - but anyway: THAT’S NOT A CARTOON!?

I love insightful works like that (edit: I mean the video that you linked + Innuendo Studios, not necessarily all of those above), which see so much farther than the rest of us that they are able to complete the circle and wrap back around and parody it for us to see it also from their POV:-). It’s outright infectious, b/c once you outgrow something by seeing The Truth, you can literally never go back to the way things were before.
