Quite simply, the special effects are unbelievable in this movie. You just have to admire the realism and the accuracy of buildings collapsing, a tsunami, the Hoover Damn being destroyed by an earthquake. The computer generated effects actually make you believe that you are actually there in the worst disaster in world or American History. God forbid something like this ever happens in this country because the economic damage to this country would be beyond repair and the loss of life would be staggering.
As far as the story for this movie, there really isn’t one, but that is not the point of a movie like this. This movie is about special effects and I recommend this movie based on the special effects only.
