I have seen this movie twice now just to make sure I had a decent understanding of it. It starts out interesting but very soon takes a weird and dark turn. This movie kind of reminds me of certain Spanish movies where the outcome is just all kinds of bad. Lots of anxiety, creepy lighting, and sadness, and no glimpse of hope. Depression and a quite precarious sense of being accompanies this film, and the lighting and setting doesn't help. Creepy glass and dim lamps pair with the sad and oppressive theme. To its credit, certain scenes are for sure creepy and "jumpy" like the ones with the "demons" appearing outside, but for me anyway, the jumpiness of the lead character and his manic crap made me nervous and just took away the fun of an otherwise good horror flick.
