Dylan S. Pumpkins’s review published on Letterboxd:
Pretty standard exercise in modern horror, where every other scene is a well telegraphed moment to startle the audience, until about the very end where the personal stakes and visceral scares that the precious two main installments excelled at start to entwine to riff on key moments from The Exorcist and The Shining to great effect. Vera Farmiga and Patrick Wilson continue to be most reliable part of these movies and this is certainly no exception even if their characters are lost in the shuffle of a lacking script. Disappointing, but par for the course from the director of a lower tier Conjuringverse movie. Put Gary Dauberman in the director’s chair and cast Christoph Waltz as Hans Holzer for the fourth one so we can get this train back on track.
