Robin Solsjö Höglund’s review published on Letterboxd:
We open on a scene of utter devastation, and then we backtrack to find out what has happened. I was expecting a bit more of a horror angle. While it does get horrific, it was quite a lot more grounded than that. Noomi Rapace does a solid job as the mother who buys a baby monitor to watch over her son. She begins to hear disturbing sounds, perhaps there's someone else in the building causing them? I never quite felt that this film sinked its hooks into me, and that it's been done quite a lot before. Even so, give it a chance if you're up for a worrisome psychological thriller, just be ready for both Swedish and Norwegian dialogue - while I understood Noomi perfectly, I had to concentrate to pick up on most of the Norwegian.
