This was genuinely amazing. I can't believe that such a touching film could be tucked away in such a hidden avenue of Japan. I highly recommend anyone capable of seeing this in person take the chance. "Supposedly" this can only be viewed at a Museum once every six months but I'll give you a hint - you can find it online if you search enough!
It says I need more information so I will add that the love between a lowly diving spider and a water strider is so beautiful it's hard to beat. I felt this movie was more touching than romance movies 10x as long as it. What a unique and beautiful piece of animation and narrative storytelling.
you will not regret watching this any way you can. Even if it comes from a shoddy cam rip. Watch this ANY WAY YOU CAN!
