Bought this movie (honestly) as a filler to achieve the free shipping. I knew of the movie, although never saw it. I hoped that it would be entertaining, not expecting anymore. It turned out to be just that. The story is mediocre, the special effects are fanatstic and over all, it was pretty entertaining. This movie certainly gives us some (rather sensationalized) food for thought as to what today's severe weather previews may lead to, down the road. Again, rather SENSATIONALIZED.
This DVD was bought at $7.96 which I feel was a good buy. Anything more than $9.99, you might want to think about, unless you are already a big fan of the movie.
I would recommend it as entertaining on the same level as say... Bruce Willis' Armageddon. You can't take it too seriously but it is a good way to entertain yourself for a couple of hours.
