Despite everybody saying it is predictable and childish, I found it really deep and aligned with the onion glass concept. The center, aka mistery to solve, is not the topic of the movie, instead the decorations, illuminations, society critic andfuture technologies involvement are the real movie. Even the changes in the main character personality changes makingb him more human, with failures and the end, more layers is what makes it interesting. I really enjoyed this one.

I recommend re watching it looking at every piece of art, and color setting it is a really beautiful movie, there are a lot of gems hidden everywhere.
