The monster's motivations are never revealed -- it's just a force for the horrific.

First apparent explosion jars the camera, shuts down power, and leads characters to worry about an earthquake or terrorist attack. Later images recall 9/11 in NYC (building crumbles; dust cloud sweeps through the street; people run, scream, and stumble). TV reports show fires and buildings and a bridge collapsing. Large reptilian monster is occasionally visible (roaring, smashing buildings); smaller/sharp-toothed monsters attack protagonists in a very dark subway tunnel. Most of the action focuses on victims panicking, with loud smashing and booming on the soundtrack. Military assaults (explosions, missiles, gunfire, bombs).

Early scene shows a naked woman in bed, her back visible. Party scene shows woman's cleavage, especially as the cameraman is drawn to women's bodies (his shifting focus serves as light comedy).

Repeated uses of "s--t," as well as "hell," "goddamn," and some slang ("douchebag").

Some brief background shots: Aquafina, Mountain Dew.

Party scene shows drinking (beer, liquor) and a bar stocked with bottles.
