Film made from books tend to not even tell exactly the same story and that's my main issue with why movies are commonly not as good as the book. The movie tells a different god damn story than the one it was based on. Or at least significantly change things that didn't need to be changed just because of the medium.

Ready Player One, for example. The movie is absolutely terrible compared to the book and one of the things that really sucked about the movie was the lackluster way it did every single visual reference made in the book. The protagonist's avatar in the game of the book was basically an amalgamation of like 10 different popular fictional characters. They had a fucking additional race scene in the movie but didn't even use the car he was described to have had in the book (a mix of the ecto1 and back to the future delorian).

It should be pretty easy to match what people imagine reading the book here, since everything was just a clearly described video game or movie reference. Hollywood still managed to fuck up the visuals in their visual medium version of the story, while also changing the story in a lot of places in ways that didn't need to be changed.
