This film is horrifying no doubt but a clumsy incoherent pacing ruins this amazing, shocking nightmaric vision of a movie.
Damn bih, people compare this to Hitchcock? Nahhhhhhhhhhh, it is honestly nowhere near being like Hitchcock, because Hitchcock said that a good tool in film is to show the audience what is happening. This movie doesn't show you what is happening and it keeps you gripped to your seat until the very end.
I'd not rather say nothing else about since this is maybe a jewel in pyschological horror and you should go in blind for your first time but I can say it's a slow ass burner that slowly melts away into a satisfying and unpredictable ending,
