of course its a doom movie, its about a Nuclear war, however it real gets to the heart of what we the human race can do against each other, i.e its not about just pressing a launch button, its about how we can really send us the human race back to the stone age, and for what? a country, a idea? for oil? or just we dont like you...The movie is bascially telling you, no one wins in a nuclear war, we as humans all lose!
