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?
Eragon. Sooo much changed, cut etc, removed so much depth and story
I’ll say one thing for the movie: they cut off the sequel hook. So I don’t think they expected it to do will enough to adapted book 2, which is a level of honesty most badly adapted kids movies lack
I saw the film before reading the books, I was so furious afterward reading them. To be fair though, I think a film was a mistake. So much depth to the world it would be better served as a series. Could have got 8-10 solid seasons.
