I thought the movie was very realistic and authentic. If you're looking for something "Die Hard"ish then you're out. This is how it would really happen, more or less. It brings up thoughts of why radicals live in our society, and why they do the things they do to innocent people (although it certainly doesn't explain them). For anyone who's a pilot I believe it is even more enjoyable, because you can understand most of what's happening in the cockpit. I would venture that this is why uninformed people, especially critics, do not get it. I for one think it's very much worth watching
