I think mine’s Z for Zachariah. The book is insane. A psychological survivalist thriller between a 14 year old girl and a strange man with unknown intent. The movie is… not this. They changed everything meaningful about the characters and lost all the tension. Hope someone does it properly one day. What’s your adaptation peeve?
For it to be a great adaptation it needs to be faithful. It can be a great movie, but as an adaptation it sucks BECAUSE it’s not faithful. That’s how i look at it.
