The story is really interesting and shows how history is never just black and white.
I bet a majority of people don't know how that Marine Corps monument came about, or the complicated history of that story - that there were 2 flag raisings actually - and why. Also where the confusion lies in which soldiers actually raised the flag and when, who was under fire (from the snipers) and who was just under vanity orders.
And I love how Letters and Flags combine to show both sides' perspectives on the same engagements.
Clint Eastwood did such a fine job on these movies!
