Psychological horror is one of the toughest to pull off, you can easily be doing stupidity in the name of attemting this genre. But the writing and screenplay of this film never lets it backfire. The plot is interesting, the occassional disturbing scenes work towards establishing the horror. Its not a jumpscare film, mind you, its a lot mature than that. The performances by the cast, especially by sophie wilde is one of the strongest points of this film. The screenplay is able to cinfuse us thriugh the intercut of reality and illusion and hallucinatuons. The use of dream imagery is wonderful in this film. The cinematography, specially the two long shot scenes at the terminal ends is too good a piece. My only gripe being the lack of emotional connect to and for the characters.
