High-Rise (Blu-ray release 2016-7-18) is adapted from a 1975 novel.  In this movie, power outages cause social conflicts between residents of upper floors and lower floors to escalate into an orgy of violence.  As a cult movie it does have memorable violent scenes that I cannot describe with simple words.  Many critics love it, but I cannot appreciate it due to its lack of explanation or logic of people choosing not to go out for help, resorting to eating dog food and selling their wives, even when a police officer comes from outside to inspect.
