So I'm giving this book a three. No wonder it's the only movie series I've ever heard of where they aren't making the last movie. It has a good premise, great ideas but just poorly executed... 
 Sigh... This follows every single dystopian formula everywhere, except there isn't a love triangle! That was a present surprise, but I wouldn't be surprised at all if one shows up in the next two books. Also, why is this series three books? After finishing the first one, I don't exactly know how everything is going to stretch into three? I feel like the author could wrap this up in two and call it good. 
 The characters are okay, Tris I feel like needs a bit more character development. She has good intentions and motives, but she feels hollow to me slightly. Four is, the love interest always is!, an enigma until later on in the novel and I didn't quite understand some of the interactions between him and Tris? They were kind of weird. 
 All in all, good characters, a good premise just poorly executed. Some scenes I think should have been cut or edited. I think I will be returning this series to my local bookstore, I Wiki'd the rest of the novels and no wonder they didn't finish the movie series!
