I felt like I was watching something that could be akin to a video game produced by the United States Army (or maybe something from Clancy). The maneuvers seems like those that I have seen in training films, historical films, et cetera. The action is what is important, not the character development, think of this movie as one 90 minute examination of modern day combat against terrorists around the world. It isn't Shakespeare, but it isn't meant to be. Don't expect intricate dialogue and philosophy.
The story was not that bad of a story, in my opinion, at least it wasn't the Rambo "I can shoot a thousand bullets and hit every one of the enemies, and then they shoot a thousand toward me, and not hit me once" mentality of some movies out there. The movie is not a perfect movie, I wont say that it is. The story deals with terrorists and how terrorists can be found anywhere and everywhere just like real life. This isn't paranoia, this is brutal fact that there is always danger against freedom.
The torture scene, I wish to point out, is not realistic. The torture of humans is a bit more complex and a lot more bloody, though I find its inclusion in the film a good point to be made--that all these liberals whine that America "tortures" our captives, when the Islamic fanatics (not to be confused by the more peaceful Islamic) go all out of their way to torture people, especially those who are Christians (which does happen, Islamic fanatical countries do go out of their way to torture and brutally kill Christians).
Most of all what I appreciate about this movie is that it doesn't degrade the military like Hollywood tries to do in so many ways these days. For Hollywood, anyone who fights against terrorism anywhere and at any time is considered "evil" and "intolerant" simply because they are trying to protect our freedom from these criminals (then again calling terrorists criminals is "intolerant" anyway, or so says the liberal media). The men who live and die and fight another day for we who are at the home front should always be respected and honored.
