Just terrible. A total waste of time. There were a surprising number of actors and actresses that I had previously thought were at least half-way decent, but for each of them, this is clearly their worst performance. Sadly, though, as bad as the acting was, it was the best thing this "movie" had going for it. This is doubly bad, as I am pretty sure the producers were banking on special effects to save the movie. But they were very disappointing, despite being the obvious focus of the film. In addition to their technical flaws, they fall into the recent trap of thinking that every big disaster scene must have some famous landmark in it. One or two can give you a sense of setting, constantly using landmarks gets really annoying. Worse, the special effects were poorly used, distracting one from the story, instead of adding to it. Which might have bothered me if the story wasn't so weak. The plot had holes you could drive a Mack truck through. And the worst part of the whole thing was the stupid lines they had. One prime example was one where a meteorologist was saying that he used to be able to count on certain things, like the fact that anything above a Category 5 storm was impossible. Well duh! The category 6 and 7 hurricanes that he talks about are impossible. You don't even have to know a thing about science beyond what the classifications are to know that. Category 5 hurricanes or tropical storms are anything with wind speeds above 155 mph. So no matter how strong the storm, it's still only Category 5 by definition. This is but one example of the bad dialog in the film. It's also an example of the science in the movie that is as bad as "science" in the presidential reports on global warming that this movie seems to be trying to satirize. An easy target, but it manages to fail miserably. Almost makes you wonder if they have the opposite agenda...
