Why do you think it’s not?
I mean, it’s one of the 2 most famous dystopian novels on the planet. Brave New World and 1984. Hunger Games? Hunger Games doesn’t even get to be in the running, it gets to fuck off to YA flavor of the month land with the rest of it’s ilk.
Jaws
The book is decent enough, needed more than a few subplots chopped, but the film is legendary.
And The Terror. The book is plodding and keeps stopping for random sex scenes. The miniseries is excellent.
