If the writer follows the disaster movie schematic you'll have a great "B" movie. It's no Annihilation Earth, but it keeps your attention till the very end, which is what these great "B" movies are supposed to do. If you are not a fan of this genre, why watch it and make negative comments? For those of us who enjoy these often silly, always implausible stories, it's great fun. Many have ridiculous special effects and that's what makes it fun. The unknown actors make it even more special because you are not distracted by a well-known face speaking inane dialogue. Just relax and enjoy the silliness.
