I don't think we should just look at how simply America was effected, but also at broader issues. For example about our actions, and ways we are exploiting other countries, our invasion of Iraq, which was based on lies. People were lead to think that Saddam Hussein, the corrupt leader or iraq, had something to do with the attack of the world trade center. Which is false.. Bin laden was the one who helped plan the terrorist attack on the world trade center. Some people even have a theory that America may have even been involved in planning the attack.. its hard to know the complete truth...
I'm not saying this movie is all negative. America's "idle" for money and profit got knocked down.. but instead maybe now this movie can give people a way to grieve and understand the impact it had on people's emotional lives, besides simply how "corporate America" was effected. Maybe the terrorist attack is a signal of the anger of how other countries feel towards us, for exploiting and ignoring them.
