This movie certainly is one of the worst thriller movies that can possibly be made and no one certainly would not lose anything if it would not exist.
The plot and characters could be described as childish, not believable and unrealistic.
It certainly is hard to try to understand what this movie actually is about in a context of reality or possibly even considering it to be art-house. The main character is cartoon-like, not having any real motives other than his sick mind. The movie kind of tries to justify his actions which is even worse.
The music, characters, plot, images do not fit together very well although I enjoyed the camera-work in a very small amount. The classical music is unnecessary trying to give this main character some fake depth, it does not work.
I had feelings of walking out of the cinema, luckily I had bought a beer so I could take a sip on most painful parts.
I do not recommend this movie to anyone.
