There is no doubt that the makers of this film wanted it to be as true to life as possible. There is also probably no doubt that what was shown on screen was toned down from what probably happened in real life.

Well I have say it I found it to be more than uncomfortable viewing, it was horrific to see the portrayal of man's inhumanity to man. If you can't stomach such portrayals don't go. I walked out after half an hour as I couldn't bear to see any more of it.

On that basis, I'm not sure how successful this film will be. I wouldn't recommend anyone to see it. Read the book instead if you want to know what happened.
