Thanks for the suggestions mate.
I do agree with your father's point not only they leave their dear ones to go to a war convincing themselves that it is for the greater good, some witness their colleagues (who are now like a family away from family) die on field and then when they (the characters in the movie or anyone else in their position) are pulled out of war to go on parades to support a cause they themselves have stopped believing in fully aware that their friends are still on battlefield fighting to survive or dying. Then when their purpose is served they are forgotten confused if they were being patronized the whole time. People might forget them but these poor souls unfortunately don't forget and wish they had died in the war. The real culprit here is the Society.
There was another HBO series called Band of Brothers. I haven't seen it but heard it was quite good.
Will add - The Pianist and The Great Escape '63 to that list.
