Persephone Possum’s review published on Letterboxd:
[VAGUE BUT CENTRAL SPOILERS]
There’s a lot to talk about here but what makes the twist and by extension the whole movie work for me is the moment the kids realize they’ve gone way too fucking far. That crucial realization keeps the film from being another fucked up “sociopath child just born evil” movie. What they do is horrific, but they know not what they do, not until it is far, far too late. They’re just kids acting out after experiencing a horrible trauma. Just old enough to pull it off but not old enough to realize the gravity of it. And while it’s not spelled out, it’s absolutely clear to me that their callousness to her distress is learned behavior from their father. It’s a movie about how trauma and family can condition you into unimaginable violence. And that’s far scarier to me than a lot of “heady horror” usually can muster.
