There are some tricky reviews here and they all have a few things in common. They're all stuck on the economical and social, if not geographical logistics of a union between Florida, Texas and California, and they're all written by Americans. As someone not connected to the States I can say I think their perspective is smeared. This movie isn't about how certain political alliances came together or why certain people engaged in conflict, testified to by the fact that you don't ever even learn the president's name let alone the political party. You might want more out of the movie asking how all this came to be and you may be asking in hope of gaining allegiance to one side of the conflict or the other. The fact is this movie is not About the Why, the How or any of that. This movie is a war documentary that happens to be placed in an environment that you are familiar with. And in that respect it is superb. The acting is excellent and as required, the cinematography is very very strong. It's well paced and well written and gives you everything it promises. I think Kirsten Dunst is not as good an actor as she thinks she is but that hardly tracks from the powerful collective performance of the four main cast. This film is about the visceral and unsettling reality of conflict, life and death, and it's brought to you in a familiar place not 10,000 miles away in a foreign land. A choice that makes the impact all the more real. Sure, doing this runs the risk of the film seeming gimmicky or like any other disaster film but I think it's side steps that with grace and deft. What you are left with his real drama, real moments, real lives and the brutality and human and inhumanity of war. Please just forget the question as to whether this could happen in this exact way and just appreciate the world in which it did.
