Fight Club. It wasn’t fun to read it felt like the author was ploying with me trying purposefully to confuse me to a point where it forced me to become disinterested. However with the movie i was captivated every second. The book’s attempt to obscure and mystify the reader might have been an intentional stylistic choice, but for me, it didn’t translate well.
Jaws is the obvious one but I’ll say Dune too. The Villaneuve version. I should probably read the book again. It is possible to have great ideas but be a poor writer. See also Stephen King at times.
