I've seen a lot of negative reviews on this film but I want to say that most of them are wrong taken opinions of viewers. Sure, everyone has different point of view and assumptions regarding things that has been filmed. Many of comments state that you will probably lose your time watching this, but you are actually not. At least, it worth watching.
The genre is psychological thriller, so the image is appropriate. Ending might be misleading, but it's all up to your imagination.
What I'm trying to say is that you should definitely watch this movie if you are looking for something different to watch for evening
If even you won't like it, you will definitely remember it
