Yeah, I heard some people walked out of Cannes film festival presentation.
"In the movie’s first dramatic scene, the boy’s mother, Djuna (Lihi Kornowski), finds the boy, Brecken (Sozos Sotiris), sitting on the floor of their bathroom, munching on a plastic garbage basket—which is telling, as “Crimes of the Future” is very much about the crimes of consumption and the system of production that led to them. "
It's understandable. Sometimes movies challenge our beliefs, status quo, and offer different perspectives on lives. I'm not a fan of horror genre but I don't think this is a horror flick per se. Anyway, I haven't seen it yet, so I should not speak about it.
