this movie have all the element i like . donald sutherland be one of my favorite actor and i like science fiction and robert heinlein be one of my favorite author . i also like horror movie . how could all these potentially great element be combine into one of the bad movie i have ever see . it be forgivable to change the story and if the change make for good filming and but in this movie the change do not improve anything . the added material be pointless as well . i could go on for many line and but this abysmal movie be just not worth waste the time . what the line . they manage to snatch failure from the very jaw of success .
