saw the interview with one of they guys embedded with this team. the story is a composite of the real people, but he said the events were pretty true to life. they wanted to show what the job was like and what kind of person it took to do it.
i have not seen the movie yet, but know some who have. i think the best description of how they felt after was "unsettled". to me, that's not a bad thing. i'll let you know what i think when i get the chance to see it
