Kerry Maxwell’s review published on Letterboxd :
Probably as good a film as can be made from the source material, a dystopian Thatcher-era Lord of the Flies set in a socially-stratified Brutalist edifice. Ballard created an unsavory cast of characters, in various states of loathsomeness, and proceeded to make them more loathsome, while he plucked their wings off. Ben Wheatley goes a long way to making reinforced concrete aesthetically appealing, and Hiddleston, Evans, and Irons are at least interesting to watch, if not engaging as people. None of the characters fare well, but having to watch the women of the high-rise being brutalized makes an already tough watch tougher. Not a feel-good film by any means, but Wheatley makes it worthwhile.
