When GKND looked like it could be a thing, I actually rewatched the entire show.
My god it still holds up incredibly well. Hell, there's a lot of stuff that just flew over my head. I am shocked that more people don't acknoledge KND as one of the earlier shows to have lore based stories and stuff. I mean, something like Z.E.R.O. couldn't have worked as well as it did in another time unless it had faith in it's fanbase
KND is like what Gravity Falls wishes it could have been with it's lore, characters and story
