Night of the Comet/Headscratchers


 * The movie suggests the comet's effects are what killed the dinosaurs. But since it reduces whatever is exposed to it to piles of dust where did all those fossils we found come from? If this comet had indeed wiped out the dinosaurs, humanity wouldn't have even been aware they'd ever existed in the first place, and paleontology as we know it shouldn't exist.
 * Dinosaurs were around for 160 million years. Only the last generation was turned into dust.
 * It's just mid-morning on the first day and Hector is already holed up in the radio station with a knowledge of what makes the zombies different? He must only have just gotten there!
 * Throwing the guns away in a city garbage can when no one is collecting trash anymore is really stupid. You'd get the same effect from leaving them in a box in the middle of the street.
 * Boy those power stations just keep on chugging, no one running them.
 * In their defense, the movie only takes place over the course of maybe three days. There's a chance that the power goes down shortly after the credits roll.
 * Why aren't the kids in danger from the disease? Isn't the haze in the air going to do anything?
