This was a great movie overall. One of the best movies I have seen lately, I wasn't disappointed at all. Although it was totally unrealistic at times not unlike most 'end of the world' movies, the special effects were so good that I didn't care that it wasn't realistic. It was also a great movie for my teenage kids to go to. I was on the edge of my seat for most of the movie! I did actually go home after the movie and looked up the Mayan calendar online.
