Instead, you get a movie that's enjoyable enough, but leaves you feeling like it could have been much, much more.

Tells a fascinating and unsettling true story, and does so well, without pretending to have all the answers.

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.
