Martijn OMG’s review published on Letterboxd:
What a disappointment this was! It's supposed to be a clever horror movie but it felt more as a modernized twilight zone episode to me. And not a very good one. I can live with a movie that has a silly premise and leaves you guessing a bit, but only if there's a good movie build around. Us fails miserably as a horror movie, there's a bit mystery but no tension or atmosphere at all and characters go from zero to ten way to fast. It's a good idea wasted by a bad movie.
