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?
Lords Of Discipline. The movie left out most of what was beautiful about the book. I saw the movie first and thought what was the point of the movie. When I later read the book and was very angry about what had been done to such an amazing book.
