Yes and no, I'd say the lore is, in potential, greater than Gravity Falls, but it felt like it was holding itself back. The show had plenty of treehouses, 2x4 tech, villains, in-universe history and worldbuilding, but those things were largely treated as one-off elements for an episode. And that's the problem, the show insisted on being a silly episodic series the whole way through (OK, there was the splinter cell in the last season). I can't really blame it, either, the alternative would most likely end up too self-serious, as much as I'd like to see a season-long arc about KND internal political drama or kid-adult geopolitics.
Gravity Falls managed more just because it had something of an ongoing plot, even if it didn't quite delve into some elements (and I don't blame it, there's no way they could have gone into the weird shit without fucking up the pacing and possibly the weird shit itself).
Why did GKND fall in on itself anyway? Just not enough hype?
