I'm going to keep my review spoiler-free for the reason that you *absolutely* must not have any spoilers going in, it's so much better without, I can't understate that enough.
Cure is an absolutely fantastic film, and it's aged incredibly well, despite it being 28 years old as of me writing this. It's shot so spectacularly, there is so much to take in, so much great imagery, it'll be a very good experience.
It's very much for an audience that can go in with an open mind and not expect specific things going in, you need to just let it run its course, and experience it. Make sure you do it in a mind where you can sit down and think about it too, you want to focus on every bit of it you can. I mostly say this because it's a film where you can interpret many different things from it, and you'll want to come to your own conclusion.
The only criticism I would ever give it is that there is a little bit of a lack of a "definitive ending" that one would like, but the way it happens is also satisfying.
I just generally recommend it a lot, and I hope you have as much fun as I did with it.
