The heat wave
As a general rule I always expect N. Cage movies to be simply entertaining and nothing else and this one didn't dissapoint. There are many threads pointing out what is wrong about the end of the world as depicted here, some of which I agree with.
The one thing that did bother me to hell was that there was a freaking heat wave and everybody was wearing long sleeves and vests and clothes certainly not fit for a heat wave.
Didn't one person on the set say "hey shouldnt they be sweating and wearing light clothes and stuff?"
