Definitely a masterpiece of a film! It's been a long time since I've been immersed in a story quite like this. Sometimes you don't need a narrative arc or plot or something like that. Even without too much this was very beautiful, very close, very erotic - but not excessive.
It doesn't focus too much on plot, but rather on the characters - they are really engaging, bright and youthful - and you feel the events could really have happened. The question isn't "What happens in it?" - it's about the characters and how they feel and their expression of love. Love they found in freedom and escaping into a world of their own.
The two of them by themselves, away from everyone else, in the beach, that is so beautiful to see. It's such pure blissful escapism - and usually people frame it as if it's a bad thing but I really love it. The scenes in it were so sunny and lovely and naked and free - it's a blend of art and eroticism that you hardly ever find. It's so difficult to find a film like this - so free in its expression of love.
Sometimes it's alright to set aside deciding whether things are good or bad, and just watch things as they are. Why can't we enjoy fiction without thinking too much? This is one of those films that got me out of the present, and got me into the past, and made me wish "Wow, I wish I could live in a place like that, in a time like that." - as if I'm missing something we don't have anymore. Nostalgia for something I've never experienced.
Something that must have appealed to me subconsciously is the movie had a Japanese director. That influenced the cultural aspect of it, and made it more free - like in anime.
