A very well built story with no lapses or overdoing. Even though the events might be familiar to genre lovers writing has managed to manifest a unique story out of traditional scares. Sophie Wilde's performance is excellent in bringing out the most intimate qualities of Mia's character. Good use of visuals and special effects along with effective use of audio effects. Metaphorically the story is telling an equally horrifying tale about addiction loneliness and a fateful breakdown. Though the movie is not giving keeping you at the edge all the time it's got plenty of newness to offer and that makes it surely worth the time.
