Certianly some very disturbing scenes of how POW were treated. Sometimes hard to watch. Not so much frightening as disturbing.
A man is seen with his legs ripped off by a bomb blast. One leg is half ripped off and the other is clean off. Both are very bloody. May be disturbing to some.
There are several torture scenes, which may be disturbing to some. In one, a man is put on a bamboo cross, and nailed through the wrists. You see the nails in him after they have been nailed in. The cross is then erected and they leave him to die.
