Damn. I had an ENTIRE, long review written out, and was totally happy with it, and then a glitch in the site happened. Bummer. 
 Well, to sum it up, it felt forced. I sensed, after reading Insurgent, that a third book was pushing it. I was happy with where Insurgent left off, and I could easily fill in the blanks with my own conclusions. 
 That being said, there was a glimmer of something great in Allegiant. The explanation given early on in the book about why the cities and factions were in existence strengthened the premise laid out for us in the first and second books. Granted, it is still a rather unbelievable one, but hey, I don't read YA dystopian fiction for its plausibility. The back story that the Bureau gave reinforced Divergent, and I think actually made me appreciate it more. 
 Kudos. 
 Many people were distraught over the ending. I purposely avoided reading reviews like they were the plague, since I didn't want something to be spoiled, but I could tell by everyone's reaction that something big was going to happen. And something big did, in fact, occur. The buildup to it, however, was sloppy and it all happened so quickly that I didn't quite realize what was happening until the next chapter started. 
 I'm okay with the ending though. Honestly. Just as in Mockingjay of The Hunger Games trilogy, not everything ends up finishing up in a pretty package. To me it makes it that much better. But, that being said, I found the journey there to be boring. The big stuff was revealed early on, and the rest in the middle was filler, giving us all-too-familiar scenes of sneaking around, lover's quarrels, and makeout sessions. Throw in the quite unbelievable plotting and execution of plans, and you've got a story that shouldn't have really happened. Or I should say, a book that was unnecessary. 
 Great reveal early on, terribly sagging and repetitive middle, and a satisfactory and unpredictable ending. 
 At least Tris and Four FINALLY got down and dirty and could say 'I love you' to one another. 
 Meh.
