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 posted this here a couple of months ago: Old Henry (2021). It’s one of the best slow-burn character dramas to come out recently, in my opinion. I would steer clear of any synopsis of this movie, go in blind and enjoy the story.
