Dr. Lewis Haynes, incorrectly named as mentioned by other reviewers, had a powerful but ignored role in helping the men to heal psychologically by explaining at reunions why so many turned on each other and acted like barbarians in the water. Most had been unaware that they were witnessing not the moral failings of their friends, but instead the effects of salt water ingestion, exposure to extreme heat, continuous lowering of body temperature, horrific fear, etc., on both body and mind. Add to that survivors' guilt and the Navy's total lack of caring. At that time nobody knew of PTSD.
Thus I mourn for what could have been done in this film. The one bright spot was Stacy Keach's acting. He was masterful and at his finest.
I believe we owe it to those who survived as well as to those who perished, and to their loved ones, to tell this story again on film, and GET IT RIGHT!
