This is a tough movie, but worthy of viewing. The redemptive parts of the movie for me, aside from all the necessary sniping to protect the Marines in Iraq, are 1) how he began to come back emotionally to his wife and children after his years of 4 tours of duty, 2) his admission to the psychiatrist that his major emotional problem was grief over the Marines whose lives he could not save (for which he felt guilty, reminding us of Schindler's List), and 3) his devotion to wounded soldiers at his home area after active service. It takes a dead person to not weep when the motorcade for his funeral on a rainy day wheels down the Interstate and into Texas Stadium, which Jerry Jones had made available to the thousands who attended his funeral. Texas withheld no honor from this exceptional Seal.
Such movies like that need to be made. To some such heroes seem simplistic and over glamorized by the movie, but the story is none the less valid and its messages none the less valid to many Americans. I have had family die in the Marines service in both WW II and Viet Nam. I myself have never served in the military. I am retired clergy. However, my brother and my uncle gave everything up for service to this country. Maybe I have an inside track on appreciating sacrifice for this country..
