Rich Cline’s review (contactmusic.com) said:
Even fans of chillingly oblique new Greek cinema (see Dogtooth and Alps) will find this pitch-black drama utterly terrifying simply because it doesn't look like a horror movie. But it is. With subtle observation and fiercely clever acting and filmmaking, everything about this movie worms its way under the skin, leaving us shaken by both what we see and how it makes us feel about the world around us.
Superficially, this looks like a happy, normal family grappling with a personal tragedy. But there's much more going on here, and as the tension builds the film becomes increasingly alarming in its implications. This is a fiercely inventive exploration of dark human urges most people resist and almost no one is willing to discuss. And as it closes in around us, we're too busy being horrified to notice that it's the combination of strikingly clever writing, directing and acting that makes it work so well.
