Mytharc

This [Neon Genesis Evangelion] is one show that -really- has me sucked in. And yes, their mytharc has to be the most perfectly constructed thing I've ever seen. :)

I think this is what you seek to avoid in mytharcs - a plot that drowns out the character-based drama and morality plays that are still Gene's finest legacy.

The mytharc is a continuous story line about the government's involvement in a plot to cover up the presence of extraterrestrials on Earth.
