The Book is awesome! Sadly in the movie they kind of mess it up a bit, but the movie isnt all that bad. I would recommand you reading the book 1st to haver a better understanding. I hate watching a movie that was made from a book because they miss awhole lot of the parts and I'll just sit there and complain about how wrong it is but its not that bad. I've read all three of the books and for people who like Divergent your not going to be happy about the ending, because I literally cried at the end of the lst book.
