I wonder if TV and movies spoiled the American imagination to some extent, even though I enjoy a decent flick as much as the next guy. Wells wanted to develop the Martians and their ships with a good deal of detail, from what I remember of the book. Reading requires us to develop our imaginations, and it's a far more individualistic act than watching a movie is. You read a scene in a book, you imagine it in your own possibly quixotic way, depending on the voice of the writer and the level of detail. Then you watch a movie with your friends. How you feel about what you're watching can color the scene, but the basic information in the scene leaves nothing to the imagination. The movies are more of a shared experience than books are.
