The Dude on the Right wanted to like "City of Ember" a lot more, but then his BFF wondered how the river of water led the heroes to a higher level and the engineer in The Dude kicked in for this review. It’s a nice story that won’t harm the little ones, but there are so many unanswered questions, even with some nice acting, that The Dude can’t recommend the movie. Visually it is cool, actiony it is fun, but logically the movie falls apart. Bummer
