Great review. I did not watch this movie, but now I want to.
Actually, I don't remember what was the last French horror movie I watched.
I learned to appreciate French cinema. For the most part they have a different take on storytelling (more visual, slower, more silences, more questions). But all the genres I have watched are aesthetically pleasing.
Thanks for sharing this review. You've sold the product and your approach to it well :)
