I have no idea how to explain a film that used dancing as another medium of expression. It's best to just experience it.
Not only was this a horrifying period piece, but was also a captivating drama of how a family succumbed to humanistic evil through radicalized Christian omens and superstitions. This film was incredibly accurate through their old English dialogue and just applying great classic horror into the cinematography, as well as bringing great story telling through the frame.
This film practically revived the genre of horror back into the modern cinema.
I strongly recommend this film to Hollywood, because we really need films like this and not cheesy jumpscares and box office driven horror. I'm probably going to replace the sheets tomorrow morning.
