The complaints you have are related to script not direction. Mood is more important then logic in a thriller.
Huh? When a science fiction picture can't even get the science close to right, it puts the whole premise into question. Even the sappy "The Day After", a hokey, made-for-TV POS about the after effects of an A-bomb attack on Kansas, had the good sense to get the effects of the Electro-Magnetic Pulse right.
It's the little things that make the difference between a flop and a blockbuster, if you ask me!
