I've never seen anything such stupid. I watched it to the end just to see how stupid movie can be. There are so many mistakes that it makes the whole story is absurd, e.g train brakes works by opposite way. The train brakes by decreasing pressure in the brakes, so the train would stop in reality. (it is done so just to prevent accidents like this) Atomic bomb can't explode due to heat, fire would probably destroyed it. EMP pulse destroys everything electrical, not only chips... And some people act like retarded or something. e.g, (I don't remember her name) refused to fly by helicopter, because she wants to find her daughter. But it would be much easier to find her from the air.
