Friday nights, Disney Channel. They pumped it this summer and it is delivering.
GF is the story of pre-teen twins, Mabel and Dipper Pines, who are sent to Gravity Falls, OR, to spend the summer with their Great Uncle Stan. Gruncle Stan, as he is known, owns the Mystery Shack, a tourist trap where he has weird odds n ends that, well, tourists like.
I've been telling people to watch, that it's like Scooby-Doo meets the X-Files. Dipper is Mulder, and Mabel is Scully, if Scully had braces, crushes on boys and wore light up sweaters with her name on them.
In other words, this show is fantastic. The artwork is hilarious, and I simply can't get enough of Mabel.
Also, there appears to be an overarching story arc, where, if you Bing Gravity Falls secrets, there are dozens of pages dedicated to deciphering things.
Do check it out.
