I was fascinated at the dystopian world of a high-rise building in the book which I read in a J G Ballard period of my youth. This film does not capture the flavour completely and does not feel totally convincing as it develops. I suppose one should not complain when the book (like much of Ballard's work) has long been thought in-filmable. Tom Hiddleston, Jeremy Irons and co are watchable as ever. This is a film you should watch if you know Ballard's work – all of which is concept driven and full of characters of muddled motives descending to what outsiders would deem madness. If you expect anything other than dystopia with characters with whom you cannot identify, then stay away. As a Ballard fan, I give it 4 stars for a more than average attempt at the impossible.
