“I thought that it was very unusual for Hollywood to portray Japanese soldiers as sadistic in today’s PC world.”
Yes; very good point. It was good that this was shown. Too many people are not aware of that; or have forgotten.
People shouldn’t complain that the movie wasn’t essentially a documentary.
Movies based on real events; NEVER show the entire life story from start to finish.
I was pleased that it was even made; and it showed what it did.
It will get people curious and they will read the book.
Yes, I would recommend that even those that read the book still see the film with the understanding that they know what the man did in turning around his life in later years, because at least it will give them some sense of what he had to endure during the war.
