From someone that has read the book

Rating: 9/10 (30 March 2018)

Yes, the film is totally different from the book but that doesn't make it bad. If anything, I think it keeps it interesting because you don't know what to expect.
There were some parts of the book I really enjoyed that they missed out on but I've learned to live with it. It could've been a potential 10/10 review but the middle was a bit slow and it was cheesy at times.
I've been waiting for this movie for a really long time and I was not disappointed.
