What? No, I understand him perfectly. See the bolded? That's what I mean when I say people are watching commercials SPECIFICALLY for the purpose of trying to Solve for X. You're trying to beat the movie before you see it. That's not the trailer's fault, because obsessively rewatching the same movie commercial upwards of 5-6 times solely for the sake of trying to figure out the plot isn't the commercial's intended use.
That you think this is what you're supposed to do is what I'm trying to point out as a problem.
Like I said, the option where you start to think of movies less as games you need to speedrun and more like stories you experience for the sake of them never seems to be even partially considered by people who love to watch trailers for movies they already know they're going to see if only so they can complain that it "spoiled" everything for them.
The entire act is counterproductive. If you're that concerned with preserving the experience, why are you watching trailers? If you're watching the trailers, why are you using them as incomplete wiki entries?
95% of all the "faults" with a commercial along those lines aren't the commercial's fault. They're yours.
For me, it's just that I watched the trailer one time, and didn't expect it to beat for beat run down the entire plot of the movie, the character beats and conflict, the villain's arc, and a pivotal set piece. It's not about trying to "beat the movie." It's about having at least some kind of freshness when going into a movie potentially blind. I don't watch many trailers. I also don't over-analyze trailers I've seen. Seeing out of context clips is one thing. Seeing clips that clearly are in context is another.
For example seeing:
Shot of Tony looking irritated: "Give me the suit back, you don't deserve to wear it!" paraphrasing, of course.
and seeing:
Shot of Spider-Man failing to save the boat and Tony swooping in: "Give me the suit back, you don't deserve to wear it!" followed by a montage of clips of Spider-Man in his home made suit "proving himself.
is quite another. This Homecoming trailer was a case of the latter. The former at least forms in your head questions like, "Whoa, why is Tony so pissed at Peter, and why is he taking the suit back," as opposed to, "Oh, Peter tried to take on something bigger than he was prepared for, so Tony is "grounding" him and taking his toys away, and Peter has to learn to be a kickass Spider-Man without the suit, and will have no doubt learned this lesson by the end of the movie." I know the journey and just sitting back and letting a story unfold is part of the fun, but I have to say it's a lot more fun when you can go into it with minimal information about the twists, turns, and flow. I can't even imagine what a trailer to something like The Usual Suspects would be like today.
This isn't our first rodeo, so most of us know how these superhero stories go, but it would still have been nice to sit in the theater July and only have a fraction of information to go off of. No, it's not the trailer's fault for existing, and it's on me for watching said trailer, but when I booted it up, I didn't think it'd show us the major beats of the film.
I look at something like Rogue One, and the only reason why its trailers didn't reveal everything was because they reshot so much of the movie that the previous trailers were incredibly inaccurate. I actually kind of liked it. I'm not saying trailers should be made up of cutting room floor footage, but I was impressed at how much I thought I knew about Rogue One based off of those trailers, to what I actually saw in theaters.
Movie trailers are notorious for over-selling their product. I just wish they'd dial it down a notch. As a Spider-Man fan, of course I'm going to be seeing this thing, that's not the point. People can still express displeasure at what they feel was the movie over-selling itself by jam-packing the trailer with information, context, and even resolution, implied, if not explicitly shown.
