Don't go in expecting Green Room. This film is more of an atmospheric, slow burn with occasional bursts of intensity rather than a straightforward thriller.
Some of the plot elements and how they are handled will turn people off but the craftsmanship here is impossible to ignore. The performances are for the most part strong and the visuals are beautifully bleak. The violence is explosive and disturbing. Fans of Saulnier, and fans of genre in general, will find a lot appreciate here.
Those who want things wrapped up neatly may be disappointed, as the themes the film deals with, along with how it presents them, warrants a second watch. It's not necessarily a story with a satisfying conclusion and no loose ends. Some of the ambiguity felt unnecessary and could have been handled better, but the script is overall solid, if a bit of a mixed bag.
Overall the film's story gets its message across, regarding the exploration of the line between human and animal, and the feral tendencies we bury deep in ourselves. It could have used a bit of cleanup getting there, but it's still a strongly crafted film above all else.
6/10.
