As a lover of movies, photography, music, special effects, and explosives/fireworks - and as a conservative Chrisitian - I can honestly say that this is a well-made movie.
Yes, it does have an anti-war, anti-white anglo saxon protestant message. Remember that most of us with access to this forum live in free countries (unlike the one depicted in the movie) where opinions and speech are protected. While I may disagree with those anti-USA anti-war anti-conservatism anti-religion points of the movie, the basic themes of government and revolution and freedom are important reminders.
The movie could very easily be redone in Arabic and serve as a rally against the oppressive, corrupt, religious-perverse governments in Iraq (during Sadam's reign), Iran, Saudi Arabia, and Afghanistan. It is quite possible that people in those countries could have access to this movie, due to the current US' beneficial presence there, and get a very positive message from it.
As for the concern of impressionable audiences: the teenage girl sitting beside me was more interested in her cell phone voicemail and text messages.. so much to the distraction of me, that I had to ask her to turn it off.
