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?
Starship troopers is a pretty good movie but it’s another example of a movie that has little to do with the source
all for the better, Heinlein’s writing is atrocious.
Easily the worst of the big names in golden age SF
