Very few famous sci-fi books get decently treated when it comes to bringing them to the screen (Starship troopers comes to mind). Like Starship troopers, the origional story and characters are largely ignored, to make an enjoyable film that bears little or no resemblence to the book.I would advise you save your cash and buy the book instead. And while you are there get starship troopers as well, it si MUCH better better (and different) than the movie.
