Death of the author, especially when it's about the studio's mascot character representing a god of death.
thrives only of a similarity which is remarkably likely to happen randomly
The two sisters are named May and May, respectively. The Shichikokuyama location in the movie is based on Hachikokuyama, which actually exists and is one of the Sayama Hills. I shouldn't even have to state that the movie is also full of what is pretty undeniably death related symbolism (aside from the missing shadows which could have been missing for animation reasons), and from that point of view, it makes perfect sense in the context of the Sayama incident. Sure, it wouldn't be unreasonably likely to happen randomly, but the movie wasn't generated randomly, it was created by people who made these decisions consciously.
Please, tell me more about why Jar Jar is actually a Sith Lord. Creating a theory that fits given facts is an easy task. I could make up an alternate interpretation ifor any given movie in half an hour. It requires only the tiniest bit of creativity. All you have to do is find reasons why your interpretation doesn't contradict things that happen. Hey, part of the movie is just a dream. Uh, how you see that? Um, uh, because character/symbol/place X does(n't ) appear in the section, and because person/culture Y regarded X as a symbol for Z, its absence/presence implies it's not reality. Person W who worked on the movie was a fan of Y, so it's likely they did it on purpose.
I could make up a story about how Spirited Away is actually about the Witch dying (getting "spirited away"), and Chihiro is actually Death, and No-face is whatever other entity i can fit in, and the name stuff represents severing ties with the living (Chihiro remembers hers because she's not living), or it represents Alzheimer's, and the bathing represents washing sins away, and the creatures represent slowly going to heaven, or a delirium, and the other witch represents the other self she has to accept, and she herself actually stands for a relative/friend/pen pal of producer/director/artist Whatshisname, who died during the production of the movie. He/she had to hide the hints carefully, which is why it's denied by the studio today, yadda yadda.... I'm making this up on the spot, and it's garbage. Whenever someone tells me why it's wrong, i can change it a bit, until noone finds anything anymore. That's when we arrive at "It's about the Sayama incident." It's not about the Sayama incident.
