""Dark City" by Alex Proyas resembles its great silent predecessor "Metropolis" in asking what it is that makes us human, and why it cannot be changed by decree. Both films are about false worlds created to fabricate ideal societies, and in both the machinery of the rulers is destroyed by the hearts of the ruled. Both are parables in which a dangerous weapon attacks the order of things: a free human who can see what really is, and question it. "Dark City" contains a threat more terrible than any of the horrors in "Metropolis," because the rulers of the city can control the memories of its citizens; if we are the sum of all that has happened to us, then what are we when nothing has happened to us?"
