Ben foster is one of the best young actors. If you've seen his movies you will know. His transformation in this movie from the black and white to the color is incredible. It doesn't even look like him. All the other actors were great. The story was a good one but yes had some slow parts. But the parts of the camp were great. So much feeling all the way til the end which was really messed up. The things they made people do was sick. But this is our history unfortunately. Definitely worth a watch.
