I've never seen a movie like this before, and I'm not sure if I will ever get to again. Overindulgent, surreal, and chaotic. Feelings of sadness, anxiousness, and small glimpses of hope. Is it perfect? No, but still a great watch.
Take from it what you will. It leaves itself open to some interpretation, but if you're willing to put in a little work, it's not that hard to understand or follow.
