Don't be so pessimistic. "Gods and Generals" was a rather conservative movie IMHO. I just saw "The Last Samuri" and even though it knocked America it's basic underlying message was conservative if not reactionary (though overall the film is a rental- not a must see). But for the most part Hollywood is a wasteland. Clancey's excellant novel- "The Sum of all Fears"- about Islamic terrorists detonating a low yield nuke in America was transformed by Hollyweird types into the bad guys being "Neo Nazis" with German accents. How pathetic!
This is an old Hollywood tradition. In the same way, all the James Bond movies changed the original villains from Ian Fleming's KGB and USSR to SMERSH, whatever the hell that is. They just couldn't STAND the idea of portraying those nice folks in the KGB as villains.
