I watched this expecting a lot of explosions and a lot of shooting. I wasn't disappointed. The surprise was that the movie was more thoughtful than I'd supposed it would be. Don't get me wrong. It's not a philosophical meditation (things blow up real good), but it does have something to say.
Here's the plot: Terrorists strike an American compound in Saudi Arabia. An FBI forensics team is give five days to investigate. Will they find those responsible? (That's a rhetorical question, of course.)
The story moves so fast that there's not a lot of time for character development, but the actors make the best of the time they have, each one adding a little touch to make us see an individual instead of a type. I enjoyed it.
