Wow. Some movies (often in such despised genres as sci-fi and horror) are widely recognized as being "about" topics that they are not really about.
As a matter of fact, Godzilla really was "about" nuclear Japan, just as, say, The Seven Samurai was "about" post-War Japan's interrogation of its militaristic past.
The above should NOT be news to anyone who knows diddly about cinema history.
Spielberg's War of the Worlds has already broken the "it's really 'about' 9/11" barrier.
