Not a book and not a movie, but that Cabinet of Curiosities series adapted a couple of HP Lovecraft stories and it was fucking terrible. There were a couple of beats that were interesting, but generally it was very faithless and the changes were for the worse. There were some excellent episodes otherwise, but I can't help but feel that they are just butcherings of much better stories that I haven't read.
Politically, it's way less bad than you'd expect, I'd recommend watching it. One of the best episodes had -- to someone as brainrotted as me -- an incredible hybridization of classic horror and battle anime logic. That one was probably my favorite one, though there was one where the protagonist looks just like the Disco Elysium guy and kind of acts like him too, and it was fun.
P.S. did you know that there are movie adaptations of Ayn Rand's drivel? If you are masochistic, they might be fun to watch
There's a old version of 'The Fountainhead' with Gary Cooper. It's a good adaptation of the ideas, and is 8/10 as a movie. Cooper was a great choice for a Rand hero.
I never saw the more recent adaptation of 'Atlas Shrugged.' Apparently they ran out of money by the time the second part came out and it looks terrible.
