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?
Yes! This was my first experience with a bad adaptation - I saw it when it came out (I think I was 7?) and it pissed me off so much. The Falkor chases the bullies thing was just ugh. Falkor was far too dignified and the point of the book wasn’t about petty revenge on bullies, it was Sebastian coming into himself and becoming the sort of person who wouldn’t even notice bullies.
