While I remember enjoying it, even on the the initial rewatch, 13 hours is not a good movie. Michael Bay does action really well, and the battle scenes are just so, so good. But everything else in the movie is thinly veiled propaganda. The bad guys sneer and don’t say much, the ex-military contractors are all heroes that can do no wrong. Even the CIA is given a glowing pat on the back for illegal activities. It’s an action movie with bad dialogue, paper thin characters, and loses all the nuance of complicated political situations.
If you want excellent war drama, go watch Band of Brothers. That mini series still holds up so well, and does not hide the messy and complicated parts of war.
