The term "spoiler" should be reserved for a reveal that actually spoils the movie; where some crucial element of the movies emotional impact can be taken away by knowing some fact in advance that is held secret through the movie.
The discussion in the first paragraph here pretty much just covers the exposition in the credits, and the material you learn very early on about one of the main characters.
I feel like treating this kind of information as a spoiler will just lead you to endless anxiety until you have seen every possible movie that could be "spoiled" for you this way. Why not just relax, accept that people are going to do some light discussion of movies, and reserve your outrage for actual spoilers of surprising plot points, mysteries solved, puzzles spoiled, and the like?
Otherwise, either you have to cut yourself off from all media and conversation that might possibly reference the movie, or try and convince everyone you might interact with, and everyone who might write anything online, not to discuss the movie. Neither option seems particularly pleasant nor realistic to achieve. I suppose you could also just see every movie you intend to see on the first showing of the opening day.
What you are doing by asking for absolutely no information at all, even the basic exposition and setup of characters at the beginning of the movie, is imposing a large burden on everyone else around you to prevent a very minor inconvenience to yourself. I understand not wanting major spoilers, and that there should be a reasonable time before discussing those points openly without a spoiler warning. But it just seems that the trade-off is fairly poor for not even allowing the most basic discussion.
I actually managed this pretty much with the new Star Wars movie - but then on the way in to find the screen was greeted with a massive poster showing lots of info about the movie. I averted my eyes. Then at the entrance there were sales staff touting character drink cups which successfully spoiled a couple of the characters who would feature heavily.
After the movie I watched a BBC program which supposedly reviewed the Star Wars franchise and promised no spoilers. Pretty much the entire plot and many of the scenes could be determined from the content they gave.
The problem I have nowadays is that trailers seem to include the entire plot, all major characters, all the best effects, all the most emotive scenes; ostensibly the entire movie in digest. These to me are very poor trailers.
Generally I agree with your points however, lambda.
But that does not mean there is not still a lot of stuff that really should be considered spoilers, and the complaints about these should not be brushed off just because you think I expect you to not mention anything about a movie. I think it's a very valid criticism when the article in question reveals something that even the trailers kept unknown by never showing that person, without any need for it in the context of the article. It's like saying "The Sixth Sense, where he was dead all along, was quite good, I loved the cinematography." a week after that movie was released. While I personally would not have wanted to know about the cinematographical quality either, I realize I can't complain about hearing something like that when reading a review or when I'm not fleeing a discussion of the movie quickly enough. I never would complain about that. But I'm sure I'm not the only one who would be pretty annoyed to read said plot detail in an article about e.g. "The decline of quality in M. Night Shyamalan movies" a week after that movies release.
To sum it up: I agree with your basic point, but I think too often people that are fine with spoilers don't care about the fact that other people have a different level of acceptance and when confronted with that simply resort to saying "Well, it's silly to have this level of acceptance."
Again, I'll except trailers for thrillers and the like, those story structures necessarily depend on twists or slow reveals for their ride to be fun or interesting, and a spoiler can absolutely ruin them. But action movies?
> I'm not going to go around telling the plot of a movie to people (that's a dick move)
I have let other people decide what they care about. I'm just voicing my opinion about it. I'm not "spoiling" anything here. And, fine, my opinion is that anyone that cares about "spoilers" has first world problems. I have been yelled at (literally yelled at, like I'd just punted a puppy across the room) because I said something as obvious as "The Titanic sinks in the end", and often from movies of similar vintage.
Seriously, don't read reviews, don't watch trailers, and don't ask people their opinions of movies if you don't want "spoilers". Most of us aren't dicks, we won't go around telling you what happens in a movie unprompted (at least, not a recent movie, maybe as a way of explaining our references to older movies).
If someone wants to go to great lengths to avoid everything then that's fine. If people want to warn their fellow "blackout" fans that's fine too. If someone wants to say something isn't spoilers and it's just an action movie then, uh, ok then, I guess.
Spoiler alert: Everybody will die eventually. That doesn't mean the journey from birth to death is pointless now that you know the outcome. Everything that happens in between is the part that matters. The same is true for good stories.
I just ruined A LOT of movies from here forward.
The "spoilers" for the new Star Wars film aren't a big deal. I knew them and the "spoiled" scenes still had a big impact on me, because that's what good film making is all about.
