Maybe I just haven't been perceptive enough or maybe they did a terrible job of marketing but I was under the impression that this was the final movie in the series. I based this idea off the fact that the final book is called "Allegiant" and they didn't put "part 1" or anything in the movie's name. I walked out of this movie feeling completely underwhelmed. The movie ended with zero closure and it answered no questions the viewer may have. The entire movie seemed like an awful setup movie for a movie that I didn't know existed. It took several google searches for me to even find that there is a movie following this one. Overall I thought it was a pretty weak attempt at the book series. Even when I try to keep this review based on the movie as it's own separate entity I can't say it was a very enjoyable. There were a couple neat little things like the small drones but other than that the special effects sucked and the movie was boring. I hope the next film can recover for me a bit of the (granted, little) respect I had for this series. I don't usually walk into these movies expecting much, I just go to be entertained and try not to over analyze but I really didn't enjoy this movie.
