Rashomon
This is definitely one of the best films I've watched so far. I went in completely blind, expecting to be confused at the end or straight-up bored, but its 1h 27m runtime felt more like 30 minutes, and I was more immersed in the story than in most action movies these days. It sparked my interest in art-house cinema, which I’d always been hesitant to get into, fearing it might be too overwhelming or confusing - but this film proved otherwise. Overall, perfect film.
