I was fully prepared to hate it, but I loved it, instead.
I have no basis to judge it by, but everything looked real enough, to me. Good acting, and very realistic. I'm sure my Iraq vets will set me straight if I'm full of it. It appeared to have been based on a real persons experience, and I would like to assume that the producers used him as an advisor on the film.
At this point, I give it two enthusiastic thumbs up.
