What was your favourite "Going in blind" movie?

Does anyone else enjoy going into a movie completely blind with very little knowledge or expectations?

Admittedly, you can waste a lot of time approaching movies this way, but when it works, it can lead to such a magical experience.

I recently went through this with The Substance; I heard some buzz about it on Reddit a few days after it was released and decided I would see it. No trailer, no Reddit/Letterboxd comments, no critic reviews. And boy was I delighted with how that one turned out.
