Tris Prior lives in a modern world in which the society is partitioned into five groups. As every individual enters adulthood, he or she should pick a group and focus on it forever.
It may be totally predictable and just a tad overlong and overdone, but Divergent is a far better foray into YA territory than Vampire Academy, or even The Host.
The climactic chases, shootouts, and fistfights have been staged, filmed, and edited with insobriety. Visual clarity shouldn't be too much to ask from these movies, even if they fail to achieve ideological coherence.
Trust me when I say that, for some reason, stick with the saga in the event that the sequels will all materialise, because the ultimate pay off when you discover what it's all for will be definitely worth it.
