2012 is basically The Day After Tomorrow, but makes less sense. There’s a disaster on its way that’s going to completely change the environment and destroy a lot of cities. The ridiculous cause of the Disaster is explained in one Mumbo Jumbo scene, and then we see characters survive that Disaster. In Tomorrow, it was something involving Global Warming that made everything cold instantaneously. Here, it’s an Apocalypse forecast by the Mayans or some shit. The pseudo-scientific explanation has something to do with the planets of the solar system aligning, the Sun sending lots of radiation out, and then apparently that causes a bunch of earthquakes, tidal waves, and volcanoes on earth.
