‘The Darkest Hour’ is really a simple science fiction flick… about invisible and thus insidious aliens, who are energy vampires. As in the case of all sudden catastrophes, be it storms, monsters or zombies, they tend to bring out the best and worst in… well, the best and worst humans.
Being unseen and energy-based make these invaders all the more treacherous. Dark as they are, they tease out the darkness in people too, their ruthless selfishness. If the aliens are demonic like Mara’s armies, this makes the humans overrun by their inner demons his minions!
As usual, a common theme in such movies would involve a band of survivors, with representatives of different aspects of human character in terms of strengths and weaknesses. After karmic ‘weeding out’ of the ‘terrible’, the remaining serve as one another’s ‘Bodhisattva’ protectors.
Unenlightened, both humans and aliens have the three poisons of greed, hatred and delusion. The insatiable greed of the energy-guzzlers left trails of energy, and to be baited. Energy was fought with energy, with the light of mindfulness. All overwhelmed by the poisons always eventually lose the war!
