This is a better produced Syfy movie than most, about an ancient dormant volcano in the Northwest from which a giant monster is awakening. The first signs are rumblings, like small earthquakes, then animals and people begin dying from the CO2 gas that is leaking from the ground. Everyone thinks it's a natural occurrence except the old father (William B. Davis of X-FILES) of the main hero. He is obsessed that it's really an Aztec monster, though that really doesn't make any sense since the Aztecs lived thousands of miles awayto the South. The first thing we see of the creature is a giant eye. Why it would have an eye if it lives underground isn't explained but I suppose it makes a cool visual, like an homage to the old 60's Godzilla flicks. But this is no "King of the Monsters". It basically looks like a mutated TREMORS creature, with a beak and tentacles, so I wasn't so impressed. And it's silly how, when it's still buried in the mountain, how it uses its tentacles to pick up and eat innocent hikers for food-- when it would need hundreds, if not thousands, of people, to fill its stomach. The movie proceeds along exactly how you think it will and it's up to the hero to make the nearly impossible shot with the missile to kill it, so it all ends with the even more expected explosion. Ugh.
