“City of Ember belongs to one of the best and most enduring genres of children’s films, in which smart kids stand up against the ignorant and aloof adult world and have a big adventure in the process. It also throws in a fantastical city, replete with whiz-bang inventions and secret societies. (…) Ember itself is fascinating, an intricately detailed set that, like Diagon Alley or the Star Wars cantina, you’d like to take a few hours to wander around in.” Katey Rich // Irv Slifkin for Video Business wrote, “this lavishly designed adventure saga from director Gil Kenan… plays like Terry Gilliam‘s Brazil — for beginners”. // TV Guide “A fun and moving family film with a subtly dark feel rarely seen in kids’ movies since the ’80s, City of Ember succeeds despite its shortcomings, not only because of its fun and inspiring story, but because most of its flaws are things kids won’t notice anyway… [T]he story spins into a classic fable; the ignorance that seemed so blissful shows it’s just one half of a coin, where the other side holds apathy and hopelessness. The moral might well be lost on kids, but for adults, it’s compelling — all the more so because we like the good people of this dying city”.
