City of Ember is a not-quite-classic addition to the genre, a dystopia that gets away with being derivative and somewhat prone to trite "thrill ride" action sequences. It could be the first dystopia many a tween or early teen moviegoer experiences, a movie about teenagers trying to save the human race.
The canned food supplies are running out. The generator that runs the lights is flickering. "Time," as the ticking clock we hear tells us, "is running out."
Whom do you turn to? The Mayor ( Bill Murray) is a corrupt empty suit, ruling by tacit fear of the unknown ("Ours is the only light in a dark world") and promising to have a "task force" look into the generator problem. The religious just smile and sing their hymn, "This is all we know," as the lights dim.
But Lina (Saoirse Ronan of Atonement) and Doon (Harry Treadaway of Control) aren't giving up or accepting the official government line. She delves into the mystery of a missing box of instructions for the city. And Doon, the son of a tinkerer ( Tim Robbins) ignores his aged, "it's not my job" boss in the pipe works ( Martin Landau) and tries to get to the generator to have a crack at fixing it.
In a just universe, City of Ember would settle in as an instant cult film, the sci-fi movie you show kids to teach them science fiction. The set, a vast subterranean Dickensian tenement, is fascinating in its detail. Kids who have outgrown but seen Bee Movie and Flushed Away may connect to this depressing but complete world where your job-for-life is picked from a hat on "assignment day."
This dark and ambitiously simple adaptation of the Jeanne Duprau novel, by the great screenwriter Caroline Thompson (Edward Scissorhands), is both light entertainment and smart, subversive literature, urging the young to think for themselves, question authority and make their own destiny. An ending that doesn't deliver a punch or a surprise notwithstanding, City of Ember is still good enough to turn on a new generation of sci-fi fans on to the glories of movie dystopias, films that warn us of how things might turn out if we don't change our ways.
