This is may be one of the most underrated movies of all time. The preview and the one word title didn't help it get started. But people who don't like this movie either didn't watch it all, have a screw loose, or don't even know what sci-fi is. They just don't make movies like this! Highly imaginative and creative story, superb personnel, excellent special effects, fantastic direction, VERY RARE. Movies like this and "The Abyss" are a rare occurence. SEQUEL SEQUEL PLEASE. So many opportunities! A cherished part of my collection.
