You have to know this before you watch this move

I watched it because of the excellent reviews. It starts as an interesting and creative film, but be aware that it turns out to be a very violent and depressing movie.
I really don't understand why some people call it a "masterpiece".
Yes it is creative and thought provoking, but if you finish watching it with a very bad feeling, then in my opinion it doesn't worth watching at all.
