Not only bad acting - just way to cheesey but things such as if volcanic ash were floating in the skies, nothing would/could be flying, if it was the end of the world as we know it, it wouldn't be just Yellowstone going off, ash would be covering the world. If Yellowstone does go, your not going to have several seconds to make a speech about what you see, your going to have time to just think - Ok, I'm toast and you will be. If your in an ash cloud and breathing, you BETTER have a mask or something or your lungs will be turning to concrete! This is a scare tactic movie and worse than others out there - Friday 13th, Halloween!
