totally agree with this and, as a Greek friend of mine once said: "Who says it's a myth? Those are Gods and Goddesses that some people still worship. Maybe we should retell Jesus?" I stopped calling them "myths" after that.
Ditto, ditto and double ditto. "Dark" retelling of anything gets me.
A lot of "fairy tales" actually are dark, extremely so. A friend of mine refused to read the Brothers Grimm stories to her children. In Cinderella one of the step sisters cuts off a big toe and the other her heel to try and fit in the slippers. (and yes, I see other's have chimed in on this)
I don't mind stories being "inspired" by another story, but I have to admit, when I see someone describing their story as "a retelling of......." I'm outta there.
