Unfortunately the movie's central philosophical conflict, between the captain and an Afghan warlord, features dialogue like "Your mission will fail because you fear death."

This is an intense, serious war film.

The action is frequent and gripping, the heroism present but understated, and the sense of tactical complexity has survived the script-writing process, so there is more geo-political subtlety than one expects from a post-9/11 American war movie.

Has a memorable story to tell but does it in an unmemorable way.
