To me, this 2012 crap is just another Y2K. As for the Myan calendar, it simply ends. That doesn't mean it's the end. That would be like me looking at my wall calendar and saying, oh crap, there's nothing after the end of December. It's all over! It's just the end of their calendar. In the end if you're a science only person then ask yourself if there's any hard evidence to support this. And there isn't. Knowing the rate of precession, anyone with an understanding of match could figure out the galactic alignment. If you believe in god, just think about it, he's not going to end the world on a day that you will suspect. He'd end it on........ Tuesday, just what seemed like an ordinary day. Jesus was asked about the end of the world. His response was that not even he knew.
As for the movie, it looks stupid to me. It looks like it's all special effects and no depth or good characters.
