Wow, what a great show. It would often go to the very edge of creepy or scary, then someone would say a joke to reel you back in.
But here's the real reason why the Weirdmageddon finale was great: The series was obviously inspired by the X-Files and Twin Peaks, but unlike those shows, Gravity Falls tied up its loose ends! They knew the ending from the beginning. They weren't making stuff up as they went along.
Serial mysteries like X-Files, Twin Peaks, Lost and 24 would throw in weird left turns and the viewer would think, "wow, that's incredible, how are they going to explain that?" And they never did!
Gravity Falls, being a limited series (a long limited series at that) threw us curveballs, confident in the knowledge that they would be explained.
Either way, really a great show equally intriguing and funny for kids and adults.
