I remember hearing about this film before its release. It had caught a great deal of flack for its use of Arabs and Muslims in particular as violent extremists. Even at that time I knew that the protests against this film were nothing more than politically correct nonsense, as even then the only trans-oceanic terrorists that existed were of the fake-Muslim variety that today we hear about every hour.
When I saw the film, I was impressed by the fair nature of the film, in that it portrayed the truth: these extremists exist in the overwhelming minority of Muslims, and that it is unwise and unfair to paint them all with the same brush. With a very good script, excellent performances and exciting action pieces, I was impressed.
Jump ahead a few years, and we see what we have learned. This film was not just an intelligent story. It was a warning sign. It examined things that people did not want to talk about. It examined things that people thought it more politically correct to ignore. It portrayed events realistically and in fact far less devastating than what was possible. If there is one thing that can be learned by examining a film such as this in retrospective of recent events, it is that our species chooses to ignore that which it does not want to accept.
Those who do not learn from their history are doomed to repeat it. Perhaps there are other subjects we should stop being so PC about and actually talk about instead of worrying about "how it will look."
