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?
The 1996 version of Emma with Gwyneth Paltrow as Emma. I don’t know what it was about the movie, but it completely put me off Jane Austen as a child and if my sister were to watch any other Austen movie, I wouldn’t stick around to watch it. It wasn’t until The Jane Austen Book Club was a movie, and I watched that, found out that it was based on a book, read the book, that I would give Jane Austen a go. I decided to start with Emma before the 2020 version came out and enjoyed both the book and 2020 version. I also felt vindicated over the fact that I knew as a child that there was no way that Emma would be engaging in archery as a past time and the book confirmed it for me. Still no idea why the archery was included in the movie.
Probably the fact that Paltrow isn’t really all that great if an actress and shouldn’t be in period pieces. Combined with Hollywood’s apparent inability to really do much with that genre without altering it for mass consumption. It messes with the story too much.
