Gravity Falls on the Disney Channel just started in July and worth taking the time to watch an episode or two. You just might get hooked.
By like a creepy one hooked fisherman or something.
Gravity Falls is part Twin Peaks, part X-Files, part Mystery Machine Scooby Doo and a little bit of Family Guy. Yes it's a comedy cartoon, but with unexplained phenomenon, monsters and backwood hillbillies.
And you can't escape Kristen Schaal's voice of one of the twins Mabel Pines. Jason Ritter voices the other twin Dipper Pines.
Definitely a highlight of summer TV.
