Think of a mix between 'The Core', Dante's Peak and 'Volcano' on 1000/th of the budget and you get the idea. How some of the actors kept a straight face, I have no idea. The script is really bad, the acting, by some is terrible, as for the effects, a 12 year old on a Mac could probably do better. Why did it get 2 stars; it was so bad it made me laugh.
