The movie is good, I got a sense of how difficult it must have been to find this pos.
What it excels at is to communicate the awesomeness of such a feat:
by the end of the story I felt very proud of every single person involved as they completed one of the greatest, if not THE greatest hunt ever!
Well we still don't know about the Paks and what their contributions were to hiding him away and perhaps giving him up? Losing the chopper was never really explained either.
Most realistic scene was forward Chapman base, Afg. That's how it happened. The MD who was going to turn on OBL blows the contact group up instead (and himself). Terrible incident I think of the two women occasionally and their great loss.
Yes it is fairly realistic and close to these characters in many moments.
But like I said the sense of how straining, difficult and finally awesome is what makes this movie great.
