I actually disagree with this in my case. I often find myself more immersed and more moved emotionally in a book than in a film version of a book.
I suppose "immersed" and "moved" are probably not actually helpful distinctions for me to make, then, since within those there are still distinct versions in each art form.
I'll modify: I think film has more potential,
ceteris paribus, to have a strong immediate and visceral impact in the moment. There's no such thing as a jump scare in a book, there's no soundtrack aiding you towards an emotional resolution, and there is no elegant and impactful merging of image and theme in the same way. A book is something you wade into at your own pace and your own comfort level, and a film is a river that carries you along, a fact which limits its impact in some ways and enhances it in others. Which I guess you just go on to say anyway:
I do think that processing visuals and sound but without the rigor of having to decode and process text can make film more immersive in the sense that you are operating more "on the level" with the film. There are just more processes that have to happen when you're reading that can make "sinking in" a bit more of an ask.
But yeah, agree completely it's a personal thing, I'm sure some people are more carried away the medium than others and personal differences have the potential to override these things, so the only thing I'd say with confidence is that they have relative strengths
in the aggregate, apart from the handful of things that are functionally impossible in either medium (certain obfuscations of plot in mysteries, for example).
Again, I think that it's down to a person's particular wiring. (But also again: I do agree that some "the book was better" is just obnoxious intellectual posturing). If someone can say why they thought a book was better, who are we to say they are wrong? I think that, for example, eliminating a powerful subplot (in the interest of a shorter runtime) is a legit complaint.
Yeah, that's a good point, there can be an addition through subtraction thing. That's generally a non-starter for someone who LOVES a bug because if you love a book you probably shudder at the idea of having less of it, even though any sensible adaptation has to cut away and plenty of them are better for it. I'm looking at you, Stephen King.
