I had initially written a review about how much I hated this movie, but I think of it differently now. This movie is very confusing from the start to the end. Sometimes we are alternating between reality and imagination, and it gets hard to keep up especially during the last half an hour. While the pacing is kind of slow, it manages to build a certain amount of curiosity in the viewer because nothing can be predicted about it. While the idea of this film is pure genius, the screenplay isn't nearly as good. It could have turned out a lot better. Seems like too much was left for the end for the 'shock value'. Both the direction and editing are lousy within the last half an hour and at the same time that is the best part of the movie. Too much happens which is difficult to take in at once and understand it. I had to go back and watch certain scenes to fully confirm that what I understood was true. However, the ending managed to shock me. And I realized how well the things were connected with each other. We are given subtle hints about the ghost and the sisters right from the beginning. I would say it requires a lot of observation to be able to figure out things before the movie ends. Since it is psychological horror, that element is definitely present in it. While I never got scared watching this film, it managed to surprise me and creep me out. The wardrobe scenes and the younger sister getting her period were both creepy. Unfortunately, this movie falls short of a few things which don't allow it to be a masterpiece. Still, the overall effort is really good. I initially felt that the movie was overrated, but it is definitely not. It has a good rewatch value because I think these kinds of movies get better with each watch.
