Ah well that's pretty much true of all old myths and stories. I know what you're saying but personally I think the variation we get on these stories in modern media is pretty incredible.

From the cheesy to the epic a lot of the books, movies, games etc. we enjoy today are just modern variations of ancient stories.

There's also a lot to be said for telling the same story—obviously the same story—with your own touch. Personal storytelling is a dying art—arguably already effectively dead. The most obvious version of this would be telling ghost stories, but who is even good at those anymore?
