I think the main concern, at least the one I fear the most, is that presenting an adaptation of a written story to the screen will provide the viewer a visual impression of the story and the world defined in the book without giving them the opportunity to make use of their own imagination, even going as far as preventing them from having one, and which will inevitably conflict with the one a reader will have prior to seeing the adapation. This has happened to me with the Lord or the Ring books; I have read the books three time over before the films were even mentioned as projects and I had a vivid imagination, populating the world Tolkien described with my interpretation. The films came, and I feel like my personal graphical view of this world has been ripped off and torn apart. I cannot remember how things were. I am a fan of the Fondation series, and I have read it twice, and I am not looking forward to see any kind of adaptation as this will inevitably be the personal graphical interpretation of someone else. Now you may argue that is it fair: this is a liberal world we are living in and if I wanted to see my graphical interpretation of it on the screen and not someone else's, I should seek to produce it before any competitor reaches the consumers first. As I am not able, nor willing to do this, the next best position would be to avoid as much as possible being exposed to any potential adaptation.
