You can only do the whole "OMFG WORLD IS ENDING" plot before it gets old, and boring, and old, and even more boring. I went to see it and I had to prop my head up half weay through the movie... Or else I would've fell asleep. It's something flashy based off a lame prophecy of the world ending on 2012; using a plot that has been used way too many times to be effective.
Do not want.
Go see something else.
