Although there were lots of differences between the movie and the book, it was really not problematic. However, the lack chemistry between Lily/Ryle and Lily/Atlas was really disappointing. Young Lily and young Atlas had much more chemistry and were much more believable actors. This is a deep book and the movie was so light. The movie gives you a feeling that it was rushed to be made. It didn’t convey all the emotions and the book in the contrary is quite strong in that field. I even felt like the actors didn’t connect to the story.
