City of Ember is a 2008 science fiction film. We enjoyed this well enough, but you cannot over-think it. It is pretty to watch, but at the end you're left to wonder how the heck they'll go on from there. It does have Bill Murray and Martin Landau and is worth seeing just for them.
Moria calls it "an amazing film" and says, "The magic of City of Ember is its creation of beautiful alternate world that lives and breathes with its own texture." SF Signal gives it 1 out of 5 stars, and their review summary says, "Beautiful filmed, strong cast, boring movie" Slant Magazine says, "Ember is a superbly crafted environment," but points out some "storytelling deficiencies". Roger Ebert says, "It's innocent and sometimes kind of charming. The sets are entertaining." Rotten Tomatoes gives it a 53%. MetaCritic gives it 58 out of 100.
