I think Jane Austen is like Shakespeare, in a slightly DIFFERENT way. I think people will continue to revisit these stories because they REMAIN relevant, regardless of how you do them.
Jane Austen is at the END of the LINE that begins with Samuel Richardson, which takes wonder and magic out of the NOVEL, treats not the PAST but the present.
You only need to LOOK at JANE Austen to see how crossed wires can become a defining aspect of romantic life. Then again, if the course of true love RAN more smoothly, it WOULD have a terribly detrimental effect on our cache of love stories.
