Robin Solsjö Höglund’s review published on Letterboxd:
Well, Ezra Miller is a pretty good actor. So is Tilda Swinton. But I can't help but feel like this is an ugly, annoying, painful movie. And I'm usually patient with just about anything - a strange, tough and depressing film can still be a good one in some sense. But this one always kept at a distance, there were no redeeming qualities, no silver linings. I honestly felt that this is the type of film that can push a disturbed mind over the edge. I'm not sure why it was made, and I don't know who would ever want to see it. But, just perhaps, if it causes a dialogue and discussion, if something good comes out of it, it has a place in the world. Perhaps that's just the thing, nobody ever talked about Kevin.
