The movie was great. John Cusack managed to get his ass into the massive ark despite all odds-typical the-hero-never-dies plot. A huge success for Hollywood: grossing in excess of $766 million, brought the crew fame and wealth, and most important of all, left a lot of us panic over the prospect of a global cataclysm in 2012.
The science concept behind the plot isn't really new. Scientists have been studying the sun for centuries. To be exact, solar cycle was discovered in 1843 by Samuel Heinrich Schwabe, who after 17 years of observations noticed a periodic variation in the average number of sunspots(the culprit behind the solar storm in the movie) seen from year to year on the solar disk.
There is also another huge flaw in terms of science concept in the movie. I have written about this in a previous entry, about the occurrence of massive tsunami in the middle of the ocean. No, the wave is harmless in areas with greater depth. It only forms its formidable height and size when it travels to shallow waters.
2012 also showcased the darker side of humanity-utilizing cheap labor in China to build the massive arks, and also the fact that no one was dispatched to rescue the Indian scientist that actually saved their ass. So instead of spending time crying over the so-called doomsday, why not we spend more time to reflect upon the darkness that's looming above our conscience?
