I'm a scientist who deals with scorpions on a regular basis. I can tell you a few things in this movie that truly just made me laugh. First of all, common scorpions do not squeak like mice. Second, they do NOT drool constantly nor do they have faces like that. All that put aside, I really liked the concept of the film. Volcanic eruptions cause massive insects and scorpions living underground to surface and prey on human beings. I really loved the train scene, a wrecked train is a buffet for the giant arachnids. I do kinda feel like if more giant bugs were included besides just the scorpions, the film could be an instant masterpiece. Of course it would need a new title, but it could make a more interesting movie. Overall though, I love it, the scorpions are neat and I love how nature can really bite back. Would totally watch this one again.
