This is the worst movie ever (maybe not, but it’s bad). There is not even a hint of the book’s quality in it. If you are not familiar with the plot, there is a city underground that is essentially falling apart, a hidden document, and two teenagers named Lina and Doon. Lina and Doon go through a series of adventures that lead to finding an untrustworthy mayor and a way out of their city. Some scenes are completely nonexistent in the book, such as the mole in one scene that chases Lina and Doon. Lina’s father had a tunnel in the movie that isn’t in the book, too. It’s crazy how much they added in. If you liked the book, don’t watch this. I rate this movie at ages 6 and up. Good movie in itself, letdown of the original storyline.
