You've all managed to convince yourself that this is some deep work of genius, but the creator himself has admitted that he was forced to reshoot half of it by his producers and that is what resulted in this boring, incoherent mess that wasn't what he had in mind for this movie at all. Even the director of this movie has gone on record saying that the second half of this movie is crap!
Stop deluding yourselves. You're all stroking yourselves over how deep and avant garde this is, yet it was forced on a director by corporate producers looking to make this more mainstream. It's ridiculous.
Maybe it could have lived up to its potential without the interference, but that didn't happen. The reality is that this is a broken mess and a failed experiment in film-making.
