I don't know....
Just let me say that I enjoyed this movie. I love cataclysmic, apocalyptic style action movies.
But the thing I just kept driving me crazy is people standing around staring and doing nothing. Now granted I've never been in a dire situation like this so I don't know if standing around and staring is a natural reaction but in a movie it's infuriating. A giant wall of water is coming towards you so don't stare at it, run away from it. If your boss tells you to push the red button, don't question him and certainly don't stare at it for a minute.
