To me some of the best parts of the book are Wanderer's descriptions of living as another species on other worlds. Very lyrical. Like watching a National Geographic Special. I hope they can duplicate that feeling visually it would really add to the movie. I think if they try to only film the aliens take over the Earth part of the book the film not be worth watching. What was really special about the book was that the author really did make it feel as if you are Wanderer and seeing the worlds through her eyes and that is very unique.
