What I have to say about this is ...
*dumps whole trunk of stuff*
Look, I have Celtic threes! Lakota fours! Sumerian fourteens! Chinese elements, Greek elements, that faerie set I got from some friends. Cherokee color symbolism, Japanese, European. Myths! Legends! Heroes out the wazoo! Don't drop the Aarne-Thompson Index on your foot, that fucker's heavy.
Analyzing entertainment is so much more fun when you have ALL THE TOOLS. There is no such thing as too many tools! You can have fun explaining the same show six different ways. \o/
If all you have is a hammer, then every story looks like a nail, which is ... really fucking dull, why would anyone keep watching. Oh wait, maybe that's why some people don't read books. 0_o
I'll just be over here enjoying my toybox of cultural everything.
