It's not easy to watch. The story, as it unveils , makes one clinching hands and seems to affect viewer physically. It's graphic but remains real, almost like a documentary. There's no music (as a film score), no chance for even a short break from heavy grip of what seems to be reality. And I believe it is reality, with fictional characters and acted out (in a most convincing way). It's a reality that you won't normally hear of, unless you know someone who's forced into it. That's why it's definitely worth watching, worth grinding your teeth in discomfort. Hopefully, it will at least make us think, feel and act differently when next time we encounter someone from that kind of reality.
