i personally didn't like it, i thought that the writing was bad and that the plot was a bit out of hand. there was also no character development for the antagonists, it was just a sudden change, rather than them either working up to their evilness or them always being a villain. i also would have liked to see a lot more of the other characters, not just tris, her mom, and four. i would have liked to see more of celeb, and tris's dauntless friends (but, of course, they die). divergent had a lot of potential, but it was put to waste instead. :({
