Volcanic ash from a massive eruption in Yellowstone Park, engulfs the earth, creating a disaster of epic proportions. The beginning involves government leaning heavily on the geologists for a best case scenario, in order to avert panic. The scientific "think tank"s computer model suggest a much larger event, yet they yield to political pressure, downplaying the danger. Curiously, this movie seems very believable, as to how the world might react to an unprecedented disaster. "Supervolcano" is pessimistic, almost to the extreme, yet still fascinating. The movie gets high marks for realism, and viewer involvement. - MERK
