The no ending/ending was a real gut punch for me. Having wasted nearly 2 hours of my life to watch all the different perspectives from the POTUS, Security Advisor, FEMA, Military, etc. only to be left with NOTHING. It's like the screenwriter simply gave up, they ran our of money to actually finish to film, or it just got too long from too many perspectives they said ok let's leave this cliffhanger that could have been addressed. Save your time...
