Skeldal’s review published on Letterboxd:
This is not easy because there is so much good in the film. Reasonably well directed, good performances from an outstanding cast and well shot. It's definitely starting off with an excellent atmosphere and setup, which is comparable to Martyrs (not the shitty remake), which you almost would think Brian Nelson and Steven Shainberg had seen before they did this.
But yet manages the third act to disappoint one after had waited over an hour to find out what the hell this is - but when it falls into place, it's predictable and unsatisfying. It's much too long. Even worse is the CGI effects, not convincingly and it's pulls one directly out from the film.
I do not mind film that a slow-burner, but this could not maintain the thrills to the very end.
