My kid has been binge-watching Gravity Falls, a Disney show. I must admit, I’ve been sucked into liking it, too. It is one of those rare kids shows that adults can genuinely enjoy.
It is kinda hard to describe - it is basically about twin kids, a brother and a sister, who spend the summer with their great-uncle, who runs a tacky tourist-trap called the Mystery Shack in the little town of Gravity Falls - however, reality is thin there, and all sorts of weird stuff happens. It is kind of like a preteen animated version of Twin Peaks with a hefty dose of H.P. Lovecraft. Some of the horror elements I’m surprised they got away with, in a Disney show aimed at kids - there are a lot of “getting stuff past the radar” moments.
Anyway, the significant thing is that it is a series written with a definite plot arc, and that plot is ending tonight with the last episode: “The Weirdmageddon, Part III”.
