I generally agree.

But there are movies that can be spoiled because of the big plot twist.

Eg. The Sixth Sense, Fight Club, to name a few (and [anime] Your Name, even the recently released Cosmic Princess Kaguya)

And then there are some movies where the plot is so obvious that you could have a LLM one-shot predict the whole thing.

That said if the movie/game/whatever is released for a couple years, I think the spoiler warnings should be optional regardless.
