Why is City of Ember rated PG?
Official MPAA Rating: City of Ember is rated PG for or mild peril and some thematic elements.
Living under artificial lights powered by a failing generator, the citizens of Ember are subjected to frequent and sometimes lengthy periods of total darkness. (For the sake of the film, they are dimly lit in order to carry on with the story.) As well, the city is crumbling from neglect and lack of fresh materials. The teens are often seen walking through the underground pipes and are attacked by a large, mole-like creature with tentacles on it’s face. Their efforts to find a solution are met with distrust and hostility from government officials who tag them as troublemakers and seek to arrest them. During their journey, they experience a wild ride down a water-filled tunnel and other moments of peril. The discussion and brief portrayal of death are also included in the script.
