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?
Ava DuVernay’s A Wrinkle in Time. It was a mishmash of the original and completely off mark. It did become a young black power girl movie, which is fine, but it wasn’t A Wrinkle In Time by Madeline L’Engle.
