I have to admit an immediate bias. When I first went to see this movie, I was expecting another cop-out movie made mainly to show off some special effects and make money off of the latest idiotic "doomsday" theory.
If the movie had proved me wrong, I would admit it, however it fit my expectations to a T, and actually proved to be worse than I thought. That's very sad, considering I had expected a movie deserving of a 5 when I went in, which is something I wouldn't ever spend money on.
My recommendation? Save your money on this, for sure, unless you have a few braincells that need killing.
