This movie sucked big time. Typical cliche disaster movie. Generic white guy has to save everyone. Generic white guy has to save his ex wife whom he happens to fall in love with at the end of the movie. He also has to repair his relationship with his son and/or daughter who hate him for some stupid reason....blah blah blah. And it was way to damn long. I watched it online so I was able to skip about 30 minutes in the middle and it was still too damn long.
This movie was way to convenient for itself. The guy that's married to generic white heros ex wife happens to be a pilot. White hero happens to go to Yellow Stone and meet a crazy hippie.
Oh and lets not forget the super science they had in this movie: A two engine plane outrunning a pyroclastic flow from a super volcano? Not only does it outrun it, but it gets taken over by the pyroclastic flow and its still able to just fly out. If a plane were to fly through a pf it would crash because the ash would clog the engines.
If you want a good disaster movie watch Super Volacano. It was made by the Discovery Channel. It has really good effects, decent acting, and the science was not retarded.
