Frankly, I didn't know what to expect when I decided to go to this movie. I have seen that some of the people I follow for book reviews have read it, and it got mixed reviews. However, sometimes even bad books can be made into good movies or TV shows. Recently The 100 comes into mind. Not a very good book based on the reviews, but I'm hooked on the show. It probably also occurred to me, because it has similar themes. Teens trying to survive in a world they don't know much of after an apocalypse.
