Too complex. Many Many plot holes.
*Spoiler Alert*
They wear masks to go into the other world but halfway through the film they all suddenly stop wearing masks? What they can suddenly breathe in the other world now?
I disagree strongly with people saying it was 'beautiful' it was a 'spectacle' etc. I feel they like it because they are pressured into liking complex plots by people who feel intelligent when they make sense of it.
Anyway, if you can't convey a story well enough in the first go, with me having to watch it many times to make sense of it, it just isn't a good enough attempt IMO
