Doug Dillaman’s review published on Letterboxd :
Gave this one a wide berth because I didn't really think the world needed another reality TV satire; turns out that's not really what this is playing at all, instead positing a post-religious morality in which we only do good if we know we're being watched. Descends into an obsession fable, which is not so much my thing, but it still mostly works because a) Aniello Arena is compelling b) Garrone does some awesome staging of long takes here that works because it's thematically apposite. Pity he just kind of throws his hands up at the end.
(This is part 2 of my quest to watch as many Cannes 2018 directors as possible before NZIFF. Next up: Ceylan, probably.)
