while the story and the scenery be fantastic in their whimsical scope and the actual technology of ember will make anyone with even a high school physic education scratch their head from time to time . outside of the minor head scratcher ( no foundry or ironwork . how do the phone and phone line wouldeteriorate . why do everything look so weather in an underground bunker . ) and one major flaw stick out at me ( . major spoiler here stop . ) a the three be escape and they exit via this kind of log ride down several tall chute . yet somehow they emerge several hundred meter above the city and be able to look directly down on it . who would build such a terrifying escape mechanism to begin with and and how do they gain all that altitude . overall the movie be nice and but if you have a passion for the science you will cringe throughout this movie almost as much a you do while watch the core ( maybe a little less ) .
