Book to movie adaptations are supposed to follow the books! Overall, yes they did stick to the plot. BUT! There were SO MANY ASPECTS that they left out. For example, in the book, Ruby was unable to use her powers because she hated them and because she wasn't allowed to use them. If that is the case then PLEASE EXPLAIN how she knows how to use them straight away?! I mean even when she does train to use them and even then she has to touch a person if she wants to use mind control on them. In the movie, we see her tell skip tracers to leave FROM SIX FEET AWAY!!! Same goes for the other characters. They all use their powers way too much in the movie. The only times we see Liam use his powers in the book is when he was changing a tire, pulling Ruby towards him, and tripping Chubs. And now we see him pull street lights down and create huge holes in the road. When we see Zu, she uses her powers IMMEDIATELY! In the books, they would never do that because they know that they have a risk of being chased after by PSFs and skip tracers!
