Watched the movie and almost immediately started reading the book. It’s interesting in the way it’s intensely similar but has a few differences. I feel like the book was slightly darker, some of the things that took place really take your breath away. But then there are some circumstances the film does better - the fact that the main guy was the son of the male principal in the book seems very specific, whereas the female principal in the film is a more likely occurance and creates a more nuanced story. But still, it’s girl power, it’s kick-ass, and it’s brilliant.
