I have no problem with people talking about the book, but to those people who have seen High Rise at festivals: STOP FUCKING SPOILING EVERYTHING.
Use tags, don’t ruin the fun for others. The movie hasn’t been released anywhere. It’s months until it is out for the public. Some people, like me, don’t want to know everything before they even have a chance to glimpse it anywhere.
We know what the movie is about, but don’t talk about every single detail and dissect every change from the book on posts of others.
Do it like other people, when they see a movie early and do it behind cuts and use spoiler tags. Don’t be brats.
