I would have gone crazy watching this garbage in a theater. I give it 5 stars for the acting of Joaquin alone. Nothing in this movie is believable, yet it's framed in reality. It was really slow and agonizing to watch. It got better towards the end, but even less believable at the same time. I don't get the "masterpiece" reviews. This was at best a fictional psych study that played on our current state of isolation and intolerance as a society.
