I feel like everyone has had a movie partially spoiled by a trailer but I also feel like descriptions, movie posters, and even genre tags can be a give away and make a plot twist or scene less impactful.
One movie I vaguely remember watching without any context was the 2021 movie Oxygen. I enjoyed it but I feel like it would have been slightly more predictable if I had looked at the genre tags and that would have effected my enjoyment.
I feel like you need to have a pretty good sense of someone’s tastes to make a “trust me”-style recommendation like this.
I thought the movie “source code” seemed stupid when I saw the marketing materials, but you should ignore those completely because the PR people literally didn’t know what kind of movie they were marketing. I wouldn’t have watched if it weren’t for a family member deciding to put it on.
Also don’t read any description from people who understood the movie ahead of time, it would spoil it. My only hint is that it’s time travel adjacent, and if you understand a bit about those kinds of theories you’ll understand the movie. The delivery is good, just go in blind when watching it.
