The beginning is cringy. He looks
like your Bruno liberal in the ranks refusing to shoot a gun. Then the antigun scene of his dad trying to shoot wife in domestic abuse etc.
However this man in reality was no SJW, just a god fearing 7th Day Adventist, who does admit that he has some kind of remorse in wanting his father dead , but you can tell Hollywood is highjacking it all. A lot of cues when in a relationship evoke some kind of cringy communist subliminal romance too, found in other SJW movies.
The battle scenes then were pretty good with BAR as the star weapon in the hands of the toughest soldier and killer who ends up being his best friend before getting killed.
Ok, what he did was maintain the morale
of the troops and restablish somekind of
meaningful work for
civilization that the suicidal Japanese soldiers without hope and plenty of cynicals lacked. They did a good job of portraying Japanese stubborn discipline as hypocritical in its rituals given no display of civilization and diversity of point of
views on their side with medics of the kind.
So the latter half is A+, the beginning is slow and filled with propaganda, giving it a C. Also we never know what happened to his brother who too volunteered.
According to an older documentary about him, the father trying to shoot an uncle is the true story, I think. It did bother him and did set him on his non-violence path.
