This film was brilliant, it has a haunting charm and is the only film (other than Donnie Darko and Hereditary) that left me jaw-dropped by the time the screen cut to black and the credits rolled.
This film has beautiful cinematography, haunting soundtrack and even better acting. Seriously, Sean Harris does a fantastic job, the way he manipulates his eyes to represent the torture his character goes through is genuinely scary.
Need I talk about the uncle character? I won't spoil anything but, Jesus, his character makes me unsettled and uncomfortable everytime he is on screen.
I love this film a lot, it's not a scary film, but definitely a haunting one.
I really don't get the criticisms: I don't see how it was boring at all, it was an hour and a half long and despite feeling like a slow burn, it has a surprisingly fast pace. It's not dull, it's bleak, quiet and grey. Also, it's not a horror movie!!! Stop saying it's a bad horror because it's a thriller, it's a study on the psyche of an incredibly tortured soul. Don't go into this expecting a horror movie.
