all the action scenes are good my overall problem with the movie is that the heads of government of the u.s were not able to make the hard choices and the sacrifices needed in order to stop the enemy, they didnt look at the overall big impact that would have happen to the world, when talking to the enemy they were giving up ground, they werent thinking of what would happen by giving what they wanted, and by giving what they wanted the whole time the nearly destroy not just the u.s but the world, cause by setting off those nukes would have made a chain reaction below the surface of the earth. but in short they didnt have resolve to make the sacrifice to stop the problem and to stand there ground, witch nearly ended the u.s and the world.
