You say it's not afraid to be about something, but what it's about is just pumping up the propaganda machine and continuing to pander to the us/them ideology that is destroying this country. To wit, Obama is not interested in peace with Iran, has put more troops into combat overseas than President Bush, is SUPPORTING a bigger and more dangerous spying scandal than Richard Nixon that has all the same qualities of McCarthyism (replacing communism with terrorist as the excuse for doing it), and has not only refused to prosecute the banks that have caused the economic problems in this country, but systematically put into place laws that further protect them from legal repercussions and allow them to continue the exploitation of the American people. If it were still Bush in office, most of the media would be up in arms about it, calling for his resignation and you'd be right along with them in the chants. But because Obama's a democrat, the media will make any excuse they can to keep from being seen as the monster he is (unless you're Fox News, but Fox is already a joke to most of the American public, so their opinion doesn't count).
I don't care if it's ballsy for Emerich to make this film about something. It would be equally ballsy for someone to make a film in which a a good-hearted, but maligned Republican president is attacked by unapologetically evil homosexual pro-abortion Muslim radicals.
It would also be equally bullshit.
