For once, I'm being trendy. I watched it while drunk, maybe it's for the better. It's supposedly very deep, but to me, it's just a collection of pseudo-philosophical clichés with a hundred potential meanings (most of which are just pretentious nonsense) that you can choose from based on your own twisted perspective. If you ask me, it's about how a person needs to eat properly, have sex, and not let themselves be oppressed, otherwise they'll go crazy and start having delusions, paranoia, schizophrenia, and other crap. But that's just my opinion, and the film is a piece of crap, twist it however you want, 6/10.
