I feel the need to write something about this book since I read it years ago but only rated it today. 
 Allegiant remains, to this date, one of the most disappointing conclusions to a trilogy that I have ever read. I loved Divergent and Insurgent because of their action, characterization, unique worldbuilding, etc....but this book fell short in pretty much every way. I remember there being very little that I liked about this; the plot felt contrived, the characters flat, and basically the whole world that had been set up in the first two books seemed irrelevant?? The ending did make me cry, but although I'm not opposed to the author's right to make the decision she did, it felt like a kind of flat, last-ditch attempt to create drama.
