Interesting. I was worried that they might replace the albatross in the Dark Island scene with her just glowing or something, but there's an albatross mentioned somewhere in there (possibly foreshadowing that part of the movie), so I'm guessing they kept it in
Anyway, I'm thinking this "vision" thing might actually work out well for the movie, if it's done in a way that doesn't seem totally ridiculous. IMO I think it's too early to tell. But from the stuff that they've decided to add (like the "saving the lost souls" thing and overcoming "the darkness within"), the writers and director Michael Apted seemed to have gotten a good grasp of Lewis' philosophy, so I'm pretty sure it will work out great
