This is another move showing how so out of touch "professional critics" are from the people. They want a movie with everything shot in the color green, 2 hours of silence, one word spoken at the end, and everyone in the audience to have experienced both an existential crisis and an epiphany of the importance of every single individual cell of the human body in order for them to give it even close to 4 out of 5 stars.
This is not that. It is, instead, something fun, engaging, and at times tough to watch because of the immediate and glaring parallels to our society. I thought it was great and way more than I expected. Had it on my watch list for a while, and oh man what a treat it was.
