Reading through the reviews, It is obvious that this movie is underrated however obviously it isn’t the best out there. Personally, I thought the acting was generally great with few wavering points. The storyline was great too and the climax was tense as the plot twisted and you were trying to make sense of things. It truly makes you feel hopeless and frustrated which is an important feature of a psychological horror/thriller. I, unlike most people, found the ending quite good because it really turned the tables and was important for understanding things but the last scene wasn’t great and unrealistic, overall this was a great movie, one that I would recommend although I don’t agree with the therapy stereotypes involved. Enjoy!
