The book was awesome, it showed the flaws of our world, but it may be as good as we can make, and that's just one thing they delved into, you won't understand how moving the book is until you read it. but, in the book, Lois purposefully made their world vague to convey that to the people in the community the world is also vague to them as well, they just don't know it, but their world is very simplistic and you always know exactly which direction your life is heading. But just because the book is vague doesn't mean you have to fill that in with whatever you want to make it seem more exiting and like a utopia. It takes away from the book, the book is supposed to make the community feel very simple, because it is, to the readers but also the characters in the book, it wouldn't take you more than 15 minutes of watching to realize they take the idea of a simplistic world without feelings and throw it into a dumpster, just because they can get away with it, and the creators of the movie take advantage of the vagueness when that is one of the major points of the book, that the world has been simplified. The ending of the book doesn't tell you what happened to the characters he left behind and his community he has left behind, but clearly, they do not do that in the movie, which I doubt many people enjoyed.
