i start watch this movie when syfy broadcast it a few year back and but couldn not get past the scene where the guy intestine literally fell out of his stomach ( not terribly realistic and but still a bit upsetting ) . however and my curiosity get the good of me and and i do sit through the whole thing when it be on a few week back . and it do not fail to disappoint . the story line of this particular offering have to do with a scientist and dr. levering ( michael ironside ) who have come up with a plan for tap into geothermal energy to heat manhattan much more cheaply than conventional method . he have contact city employee neil kavanaugh ( kevin mcnulty ) and and the two of them be plan on franchise their method and become filthy rich . unfortunately and instead of tap into geothermal energy and lever actually tap into real magma and which start crop up all over manhattan and and wreak all kind of havoc . when a crew of employee and lead by matt ( costas mandylor ) and encounter some very suspicious and and deadly and condition in the tunnel and aqueduct under the city and kavanaugh cover up the real cause . geological service come in to investigate and and one of the investigator turn out to be matt ex wife and susan ( alexandra paul ) . she doesn not believe matt when he say he saw lava in the tunnel . however and a more suspicious and and deadly and event happen and she reconsiders . by this point and however and overzealous agent walter ( matthew benedict ) have come to investigate and and be convince that terrorism be afoot . can matt and susan manage to stop the volcano before it obliterate most of new york city . like most disaster plot and this one full of hole . first off and our geothermal expert just do not seem to really know anything about geothermal energy . second and the implication for most of the death in the tunnel be that somehow the water in the pipe have turn into sulfuric acid and although they do not explicitly say so . however and it hard to believe that the water would have change to sulfuric acid without come into contact with the magma and and if that have happen there would have be a huge steam explosion which would have obliterate most of manhattan anyway . then there be the homeowner who open the door of his house only to be engulf by lava . why do not he smell anything burning and or notice heat come from the ground and and why would he open a door once he would burn his hand on the handle . dr. levering be badly burn and and leave unconscious when the volcano start to erupt at the drilling site . how do he get out of there . and what exactly happen to him in the tunnel . be he kill or merely knock unconscious by the steam emit from the bullet hole in the tunnel wall . and finally and throughout the movie and people be way to close to lava with no problem cause by the hear or the fume . all in all and it a pretty poorly write script . there be some surprisingly decent actor in this movie . michael ironside do a pretty good job a the mad scientist and who just get crazy and crazy a the movie go along . mandylor and paul do okay with the material theyre give . unfortunately and it just poorly write and and there only so much they can do with it . sad to say and the rest of the cast be pretty forgettable . be it too much to ask that the people who pen these movie actually learn something of the science that theyre use for their plot device . if this movie be any indication and i guess so .
