So, yes and no. I think that depends on how close the adaptation is going to hew to the original work.
For the Marvel Cinematic Universe, for example, what they do is only a very loose adaptation of the original comics. Referencing the comics in discussion may be amusing, but usually doesn't give away anything about the plot of the work. In discussing the upcoming Wheel of Time series, I expect discussing the plot of the book is very likely to give up elements of the TV series.
In the end, this is really a Golden Rule question. We are talking with actual people, and we should have sufficient respect for them to not ruin their experience because we are thoughtless or showing off how much we know about a source material.
Please don’t assign motivations to me just because you disagree with me.
My position has nothing to do with showing off. I’m also quite aware that my fellow posters are
actual people. My stance is about reasonable norms and expectations.
So, for a Wheel of Time TV Series thread, I would expect folks to either set up a separate thread that included book spoilers, or use spoiler blocks when mentioning parts of the books that haven't made it to screen. However, once that series starts, when an episode airs, folks should feel free to discuss the content of that episode. People like me who don't binge watch or often watch shows the day an episode drops, should avoid the thread until they are up-to-date.
Again I mostly agree, except that IMO the norm is and should be to speak freely unless the space has been designated to avoid spoilers.
I don’t actual think it’s good for society/media to even have a widespread expectation of the sort of novelty that underpins the idea of spoilers. “Oh I found out the twist in The 6th Sense. Why bother even watching it, now?” Is just not soemthing that should be encouraged as a mindset. However, I don’t imagine I can change peoples minds, so I will respect requests to avoid spoilers.
I won’t ever consider myself beholden to
assume such a request barring an explicit indication otherwise, however.
