I've heard so many mixed reviews on this and Allegiant, some say their not as good as Divergent, others say they are. My opinion is, I honestly liked Insurgent slightly more than I did Divergent. (If I could give 5 and 1/2 stars I would). It lets you learn even more about the depth of the characters. Who they are as a faction and where they come from with their families. There's a lot more action in this, than in Divergent also. I was slightly surprised with the whole Caleb thing, so that was an added bonus. I hope they do the book justice when the movie is premiered, hopefully they'll follow the story as much as they did with Divergent.
