There comes a time in a persons life where he has to give up his or her morals to do what's right. Well, Desmond Doss said screw that, and forged his own path.
Hacksaw Ridge is a remarkable tale of a man who had the almost literal crap kicked out of him for what he believed was right. Desmond Doss was medical officer in World War 2. But not just any medical officer, Doss didn't carry a gun. Mainly because of his faith. In the Bible, it says "thou shall not kill". And Doss took that to heart, and payed the price.
The movie has you in awe of one's will power. The ability to prove that anything is possible with God (or whom or whatever you believe in). Mel Gibson really has knocked it out of the park with this one.
P.S. I liked Andrew Garfield's role much better here than I did in Silence. Sorry not sorry.
