I can think of about 2,012 reasons why you shouldn’t watch 2012, but I will spare you the full list for right now. The whole “end of the world will happen in 2012” mostly came about because the Mayan Long Count calendar ends in December of 2012. So is this going to be another Y2K scare or will the Earth really end? Who cares, but in the movie 2012, the earth really gets effed up and a metric butt-ton of people die.
