I'm way too sensitive to these kinds of movies, I cried at the beginning and when the violence started. Mostly because there were people cheering in the audience, and all I could think was how someone could want to hurt let alone kill another human being. And then when I walked out of the theater, there were people saying how cool it was and that it should happen. I feel like a lot of people missed the message beneath everything, that the value of a human life is incomparable to anything, and being rich and well-educated does not always mean that you are a good person. I don't know, that's just something I got from the movie.
But the acting was good, and it definitely had suspense, I personally just disliked it.
