Example of one response:
"I went into this story very engaged and interested, and slowly grew disengaged and irritated as I progressed through the nearly 500 pages. Below, I outline what I thought was good, bad and ugly (i.e. completely unforgivably bad). A faction without rules?: SPOILERS: I completely did not believe that Dauntless would be governed with absolutely no rules or consequences. It was absolutely ridiculous. I found is unbelievable that initiates had to beat each other to unconsciousness, repeatedly, regardless of gender and size.
RESPONSE: Yet, in a dystopian society, the idea that there are no rules or consequences is not only believable, but necessary. The lawlessness world of the Dauntless is believable (because of the lawlessness of our own world IN SPITE of our rules) because there are so many people in our world that crave acts of violence and cruelty. For example, when Peter committed two felonies and was not put on trial, he exemplifies the many athletes that go out and commit acts of violence even unto murder and are never even put on trial because of a lack of evidence. The Dauntless, in my opinion, carry the story and make it a great story (and remember that it is just that: a story. Things don't always have to make complete sense).
