Not trying to belittle movies. Sometimes the movie is better than the book. A book takes several days to finish sometimes. Lots of good film adaptations to books.
For example:
One Flew Over The Cuckoos Nest
American Psycho
I argue that commercial interest controls a movie. A movie has a fixed interpretation and less imagination.
I think it's worth noting that translation from one medium to another will always change the original vision.
@Ikagura's original question may be a little limited. Books aren't just darker than their cinematic counterparts, but every aspect is going to be slower and denser. That's the nature of the medium. But a movie holds its own unique advantages if the story is intended for a film.
I think you're seeing weakness in film as a medium because mainstream movies have been artistically handicapped as the industry became solely about money. There are many examples of movies being just as heavy for the needs of the intellect as any book.
Take 2001: A Space Odyssey - that is a successfully dark, dark film that stands on its own from the book (wasn't really
based on a book but the story was written simultaneously for both mediums). There's no way the book could offer the trip that the movie did, or intrigue astute viewers with the visual symbolism accomplished through
skilled editing. Despite engaging the senses, there's so much thought provoking material in the film that people continue discussing its meaning to this day.
Or how would you translate
this visual experience (I don't mean the show, I mean the video - watch it in its entirety and you'll know what I mean) into a book without losing the emotional impact it has in the audio/visual medium? I have read books, I have watched films. Neither medium is inherently better or worse or less intellectually challenging than the other.
