There is an abundance of movies loosely based on mythologies coming out these days. Take note on the phrase “loosely based.” I don’t understand why critics and other commentators take issue with these pictures taking their liberty of playing around with their source material, especially when the source material itself is not really immutable. Off the top of my head, I can’t say this for sure regarding Norse myths, but the Greeks had very diverse, and contradicting, stories to tell about their deities anyway.
Besides, I think being “alive” is the most valuable aspect of mythology, and it’s what sets it apart from normal, publishing-house fiction. Myths are fascinating not only because they’re really engaging stories, but because they’re tales that address our deepest questions about the world around us. How did we come to be? How did the sky, mountains and seas come to exist? Why does the sun rise from the east and set in the west? Mythologies reflect the hopes and dreams of the societies that created them. They’re social products in the fullest sense; they’re genuine records of culture.
