Buffy Without Joss?

What would a Buffy the Vampire Slayer movie be without Joss Whedon? Or be without the story he built up over these years? Apparently the original movie director is thinking about doing a remake without Joss. I think now that Buffy has built up a large following (of which I am one) they can't go backwards and flush all that Joss Whedon has built. What do you think? Will it survive without him?
