If you have nothing better to do... I give it 5 stars for being such a hoot. This movie has every, I repeat every, cliché in disaster films. It is like a textbook on the prototype. I must admit that there are touches I haven't seen in my favorite volcano movie "Dante's Peak", like the rubber duckie. And having lava come out of your front door! Otherwise, it's all there--the politicians who don't want panic in the streets, like "Jaws". The overbearing FBI agent who won't listen to anyone, the hands- on experts who were once married ("Twister"), the crook trying to make money on a hazardous scheme...
Watch it for the laughs, but don't spend money for it.
