One single academic paper on Gravity Falls, since 2014? One. One. And even that fails to mention Lovecraft. Odd, as there are some fairly large clues in Gravity Falls, on that particular influence…
Anyway, the one paper I found is: Lorna Piatti-Farnell, “What’s Hidden in Gravity Falls: Strange Creatures and the Gothic Intertext”.
Checked for others: Google Scholar, Google Search, Google Books, and JURN. One other paper proved to only be a slight abstract for a conference paper, on the changing status of animation in general.
Which means there’s huge potential here, I’d suggest, for independent scholars to publish a thoughtful book that tells academics to wake up and smell the popular culture.
“There’s never quite been a show like Gravity Falls” — Nerdist.com.
“Gravity Falls is the best thing on TV […] consistently, laugh-out-loud funny every week [yet] It’s neither vulgar nor stupid […] I don’t care how old you are, if you’re not watching Gravity Falls you’re missing out. […] the perfect TV show.” — Forbes.
“Saying goodbye to Gravity Falls is like saying goodbye to childhood all over again […] something that’s almost unheard of in entertainment […] uniquely wonderful” — Polygon.
“Gravity Falls is a clever, clever show [that] takes care to layer its delivery, slowly building nuance, offering relatable scenarios and interludes of silliness to balance out its more philosophical elements. You need to watch Gravity Falls […] the narrative arc is positively balletic in its elegance.” — Ars Technica.
