all the Mexicans in the theater erupted into loud applause at the bit where Americans were border jumping into Mexico and the reporter said Mexico won't let them in unless the US forgives all loans. I walked out. Would've walked out earlier but I wouldn't have got a refund, so I tried to stick it out. It was kind of fascinating if you looked at it in a detached way, like a study on propaganda. (which basically that's all it was).
You give Emmerich WAY too much credit. Its a popcorn thriller with a plot ripped from events current at the time or writing. 2012 is the same thing. Emmerich and his crew make shit up as they go along with the plot and use whatever angle works for the time. Whether is alien invasion (ID4) giant monsters (Godzilla), global warming (DAT), or the BS with the world ending next year (2012 of course). You're reading way too much into the movie and applying a level of depth to the film that is far beyond the reach of anyone involved.
