The greatest strengths here are the excellent performances from the two leads - who do a lot with very few lines and have such great chemistry on screen together. The cinematography is also beautiful, lending a heightened, poetic sensibility to the story. I think that sometimes the actual 'message' of the film feels too blatant, while also feeling somewhat muddled by the ending. Certainly a film that deserves to be rewatched and that deals a real emotion punch. The nuance of that punch is debatable, but I think the purity of the emotions and the sincerity of the story make up for that.
