I finally saw it. It is a war movie about Iraq. It does a good job of looking like modern warfare...and that's about it. As a movie it did not do what great movies do. It did not reach out with a great character or story or moment and grab you and hold you unable to look away for fear of missing something.
To the contrary, it followed some pretty set tropes: Person near the end of retirement in the line of duty; concerns about trusting the locals and/or humanizing them; contending with what it means to put your life on the line day after day. And I didn't see much to deal with these tropes in a new and interesting way.
Oooh, a female director. I am a big enough feminist not to care who directs my movie - boy or girl. Please just make it good.
