It's such a MASTERPIECE. I had watched this movie few years back and yet when I think of it today, it gives me thrills that I decided to watch it again. Everything about this movie is GENIUS. The small little details, the characters, the story itself that revolves around a plain fact that we all missed despite of it being there all the time is what makes this movie BRILLIANT.
It's not some typical horror movie that will make you jump out of your couch, Instead it's a psychological thriller movie that you can also relate to the real world. The connection between the two main characters is MAGICAL and how both of them helped each other to look at the bigger picture throughout the process. To sum it up, I would just say it's beautiful and magical and everybody should watch this movie at least once in their lifetime.
