Eh,it was OK. This series isn't a favorite of mine but I'll keep on with it. 
 When I first opened up Insurgent, I had I relearn who everyone was. After Divergent I just forgot about everyone. 
 I didn't really enjoy Tris or Four but I loved all the characters surrounding them. They're so much more interesting. I'm SO much more interested in learning about her parents. That ending slightly irritated me, it felt like as soon as things were getting interesting it was over.
