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?
I enjoyed the film when it came out (probably because I was about 8 and hadn’t read the book yet), but on rewatch it is really quite bad. The opening act is decent enough and does well to capture the feel of Lyra’s world, but the pacing later on is atrocious. The last half hour of the film probably needs to be three times as long, it’s just so rushed. And I’m not sure why they removed the ending of the book, especially since it would make it very difficult to set up a sequel
