I see no one has posted here for awhile, so I'll bump as well, since I've read a few books recently.
A couple months ago I finished the Divergent series, slightly before the film came out. Having read all three books, I'd have to say that the ending was pretty disappointing. The first one is an interesting look at a dystopian society where everyone is forced to choose a class or "faction," based on one of five predefined positive characteristics they feel they excel in. They are then required to be initiated into their respective faction, and those who fail become part of the "factionless," who live in squalor and poverty. To be factionless is seen as worse than death, and many express their desire to die rather than join them. It has an interesting premise which transitions relatively well into the second novel, revealing a gigantic and unexpected plot twist at the end. Unfortunately the third and final novel starts to fall apart when too many different plot points and scenarios come into play and the ending leaves the reader with little change in the outcome of the character's choices. As for the film adaptation…it had some good cinematography and decently choreographed action sequences, but was overall not worth watching for the admission price.
I recently picked up the Maze Runner Trilogy due to an interest in seeing the upcoming film. I'll post here again after I've read through them as well as a small review on the movie if this thread is still active.
