I watched three war-related movies over the last few weeks.
Restrepo (2010 documentary) - This one was by far the best. It was made by Sebastian Junger (a journalist and documentarian) and Tim Hetherington (a photojournalist). They spent a year in Afghanistan with a platoon in one of the most strategically crucial valleys. It's just a great overall view of life for soldiers in a war. I found it to be very neutral, which is very rare for documentaries these days. I completely recommend this one.
Redacted (2007, fictional war drama, written and directed by Brian DePalma) - I just watched three youtube clips to use for this post, but all of them make this movie look MUCH better than it is. So I don't want to mis-lead you. The writing and acting/directing is so steeped in stereotypes, it's really belittling to the story (based on actual events) and the people who are part of the military.
The War Tapes (2006 documentary) - Filmed over the course of one year by soldiers in Iraq. At first I didn't like this one as much as Restrepo as it seemed to focus on poorly educated yahoo's, but that was just one part of this movie and as it progresses, we get to see these men in a different light. Restrepo has a broader view of war and the men fighting it, whereas The War Tapes focusses more on the lives of the men and what their lives are like, both during their time in Iraq as well as when they go back home. So I recommend this one and Restrepo, but avoid Redacted like the plague.
