Have you seen the movie? Did you like the movie? Were you confused for how certain things worked or what to know more about the character and world?
Well then pick up this book in which the entire movie is expanded on. We get to learn so much more about all the characters and their inner thoughts. It follows the book fairly closely with a few changes here and there.
Reading this without watching the movie? I think it would still hold up, though I liked also having a visual picture of the fights and how people looked. The voices for the audiobook weren't great but not terrible. If I would read it again I would likely just pick up the book though.
