A movie like this was inevitable...
Of course drones are gonna be used as a name for the consciousnesses of an evil serial killer...
And its a double reference because the drone is not lizard vril but a piece of technology that consciousness has been recorded to.
Pretty fkin advanced drone to be able to whole an imprint of an entire consciousness on it.
Last i heard the human brain is equivalent to data in the region of petabytes each of which is more than a thousand terabytes but i imagine they won't go into that.
