2 it is! The perfect grade for this movie! Why, you ask? Well, let's see, the subject is horrible, overly used, and executed not in a horror like style, but torture porn. The acting is let's say somehow acceptable, a little over half of the movie nothing happens, sure, they may have tried to build some character depth, but I think it ultimately failed, cause you don't really get to feel much for anyone. Just hate the main one and move on.
So yeah, I guess the movie has one solid performance, as you do get to hate the main actor, but it could also happen cause the movie is so bad and he is the face that appears the most, so making a bound between these two, you end up hating the movie, the always there face and voice and the fact that you wasted your time on a movie called "Children of Sorrow"!.
What can I say? Bad choice...these things happen. But hey, you live and learn right. Anyway, don't let others make the same mistake. Warn people. Absolutely nothing to see here, stay away! Far far away! The movie takes place in a desert. So just leave it there!
