In the future, 100 years after the great war, divergent people are hunted down.

Rating: Null/10 (16 August 2014)

Divergent: differing from each other or from a standard.
That is the main theme of the movie. In this future dystopian Chicago, over 100 years after the great war destroyed most of the world, the city is partly in ruins and has a great protective fence/wall around it. Society is divided into 5 factions, according to the person's characteristic strengths. A few don't fall into any category and become factionless, essentially homeless. But "divergent" people occasionally are born, they don't have one strength but several and are looked upon with great suspicion and distrust.
Shailene Woodley is really good as Tris (short for Beatrice) who, along with her brother, are entering young adulthood and along with scores of others are being tested. But her tests are inconclusive, because she is a divergent. But she must not reveal that, otherwise there is a good chance she will be killed by the authorities.
Tris chooses the Dauntless faction, they are brave, nothing scares them, they shy away from no conflict and their job is to keep Chicago safe. Much of the movie deals with the rigorous training for several weeks, during which Tris exhibits some problem-solving skills that makes other suspicious of her.
Theo James is one of the instructors, called Four, for his four fears, and he and Tris become attracted to each other. Ashley Judd is good as her mother Natalie, who it seems also is a divergent, only revealed to her daughter near the end.
My wife and I watched it, she had read the book maybe 18 months earlier, we both enjoyed it.
June 2015 edit: We just watched it again after 10 months and enjoyed it even more this time, knowing the basic story. Looking forward to the DVD of the second one.
SPOILERS: There was a rebellion, a faction was trying to take over society leadership and Tris and Four got caught up in the effort to stop them. They were able to avoid the effects of a serum because both of them are divergents. In the fighting both her mom and dad died, but she and Four survived and squashed the rebellion. As the movie ends they have hopped a train and are headed to the perimeter, probably to the outside world, setting up the sequels that are in the works.
