The series is about to end, but I only recently started watching it:
Ten reasons why I recommend
Gravity Falls:
1- Though it's a Disney series,
Gravity Falls bends the rules of what a Disney animated series should be.
2- It's basically X-Files for kids, but there are Illuminati symbols all around. (Especially the eye-in-a-pyramid symbol, which eventually gets revealed in the series.)
3- There are codes and cryptograms scattered everywhere, some of them backmasked.
4- The story is based on the real-life experiences of director Alex Hirsch and his twin sister Ariel.
5- The regular voice actors are all adult comedians (Jason Ritter,
Kristen Schaal, Linda Cardellini, Niki Yang).
6- Big name guest voice overs (Neil deGrasse Tyson, Mark Hamill, Larry King, Lance Bass, Weird Al Yankovic, Louis CK, Jennifer Coolidge, Nathan Fillion, etc.)
7- The comedy of
Gravity Falls is for all ages, though a lot of it can only be gotten by adults (again, bending Disney conventions).
8- The story is serialized, and the characters encounter: at least two hauntings, a zombie horde, clones, Boy Band clones, psychotic video game characters brought to life, a merman, a secret society, the 8 1/2 President of the United States, a spider lady,
a literal god, parasitic gnomes, giant robots, a tribe of manly minotaurs, a tribe of living golf balls, wax statues, a golem made entirely of bad candy, a chaos beast trapped in a decaying dimension, etc.
9- THEY PLAY D&D!
10- It's genuinely scary in many cases.
