Meteor, almost the end of the world. A small group in a three-generation bomb shelter converted into a haunted house. Good place for Michael Berryman, right? Wrong, Berryman had a small role in a blue prison top. He never appears like the armed individual on the DVD cover, and neither does anyone else. Now he is locked in a room and forced into cannibalism for you "The Hills have Eyes" fans. Most of the film is three people in a small room with a sad soundtrack and sadder dialogue. This makes for horrible acting with billed stars in minor roles.
I wasn't sure why a meteor explosion causes deadly radioactive fallout. If you have radioactive poisoning, taking a potassium iodide pill afterward does nothing. The iodine is taken before the exposure. Its function is limited. It protects the thyroid gland from accumulating radioactive iodine (just a small short-lived component) by saturating the gland with non-radioactive iodine. Taking the pill afterward is like closing the barn door after the horse is out.
