This is my quick airport review, hopefully it will be semi-legible. 
 Oh sequels. I hate them. With a burning passion. But we have to remember the young adult demographic is now a market and we need to follow a trend of trilogy and team Jacob t-shirts. Yes, I am bitter. 
 To be fair, advantage of sequels include an expansion to the world you fell in love with, maybe possible new points of view. If your lucky, the story will move on with new plot lines. Take Crown of Embers. Perfect sequel. How does it manage this? Every love interest dies on the first book. Every. Single. One. 
 To explain about trilogies, it is a three-act structure, like in movies. The middle of the second act to the end of it the characters are found at their lowest point. Yes, I am getting to the review eventually. I'm leading up to it. Geez. 
 So we have Tris and Tobias supposedly at their lowest, how do we get them there? Hmmm, what about ANGST. There is so much ANGST. You cannot begin to understand the ANGST. 
 This book is not BLARG. It is not swoon-worthy. We already have the two leads in love, the only place to put them is less in love. Which they keep doing. A lot. Think of Catching Fire, New Moon, or Rebel Angels. The romance is at its lowest point, the characters have already established an attraction but outside forces are tearing it apart. This is predictable, and the entire plot of Insurgent. That's it. We get it, evil government is evil. There is a great big world out there. This is glossed over and honestly, I can't tell if it's from the writing or my eyes glazing over. 
 Tris is kind of a disaster. I get the mental trauma of her previous actions, but oh my god the MARTYRDOM. WE GET IT. YOU'RE A GOOD PERSON. I loved the first book for completely edging out the softness. Lots of people die. Our characters deal with it. Now, everything Tris does is destructive and laced with angst. 
 I'll say it a million times. I love Four. Four was like my main squeeze until I read Crown of Embers. I like Tobias. I'd hit it, seriously, I do take enjoyment from his as a character. But Four, man, he was the compelling one. He had the edge and sex appeal. 
 Tobias is the sweet, caring virgin. Four is a man. Hes the guy throwing knives at you and making you prove yourself. And we got glimmers of him, like when he takes his belt to his abusive father. that got the spark back. I loved his ruthlessness and his humanity. I did not like the soft teddy bear boyfriend who cuddles and hold hands and aaaaaawwwwee. 
 No. I can't believe I'm saying this, but there should have been a love triangle. Roth clearly had two very different ideas in mind, and mushed them together. It doesn't work. I lost interest in Four. I had very little interest in Tobias. How fortunate they have separate names so I can identify them. 
 And the romance was getting to the Twilight-chastity belt level. let me say why I love Kristin Cashore. She gets teenagers have sex. Sometimes she romanticized it. But she also blazes through "virginity" and doesn't treat it like losing it could ruin you. Because it really doesn't. Yet Tris acts like her boyfriend stroking his fingers over her ribs has stolen her innocence. He gets to like 1.5th base. And they both freak out because it is 'too intense' 
 why do all YA writers think teens believe in cooties? I never did. 
 Yes, my reviews always center on the relationships, but this is what the series markets itself on. And the action is gone. It's more terrorism than anything else. We don't have this cool competitive setting. We have really complex political stuff and two teenagers turning their backs on each other on and off. JUST TALK THINGS OUT. USE YOUR WORDS. TELL THE TRUTH. 
 I can't say I loved this one. But I always hate second acts. We'll see where the third installment leads us. Hopefully we don't have another Mockingjay on our hands. 
 The problem with this book is I feel nothing. I felt nothing. It was flat and couldn't re-create the spark of the first one and that it why it didn't even try. Four stars for old times sake. Four...four stars for Four.
