The Chloë story is riveting, thanks to Exarchopoulos, who is exceptional (as usual). But the group session scenes are repetitive and ultimately trite. So a film that alternates between thrilling and irritating. Overly earnest, too. Good performances all around I guess, but those actors in the group scenes all really only have one thing to play. A true mixed bag.
The story is deeply involving and the two subjects are likable and compelling. But the filmmaking is so deliberately drawn out to create suspense and tension that it feels exploitative, and the horror movie tropes used in the “atmosphere” footage are forced and on-the-nose. Too much “directing” and not enough reliance on the strength of the subject. Maybe an hour would have been better.
