I'm not gonna enter in details or spoilers, just gonna let you now it a movie that gonna stay for you for a while after you see it. It also opens a door for becoming quite a paranormal investigator myself, looking up for all the details mentioned in the movie, and getting amazed by it' accuracy.
This film it's made to become a new classic in the horror genre, not only because it's quality, but because it's fright factor.
The first half of the movie it's paced down, let you know and love the characters. but the second half! oh boy! it's so damn chilling it will keep you gasping and crawling your hands.
Very well done
