"The screen is filled by the shot of a towering ocean wave, though it remains unclear whether we are witnessing reality or sharing in Burton's final, apocalyptic premonition."

Although not as serious as whats depicted in some movies, there still was almost 300,000 people killed from it.
"Health Minister Fadilah Supari said more than 220,000 people died or are missing, bringing the total killed throughout the region to 280,000."

If something like this ever happens on an even larger scale, millions of people could easily be killed.

The movie provides a very interesting depiction of what some A.I. drones could be like in the not too distant future. Yes, long before 2077.
