I'm not a big fan of this franchise, but the first movie was reasonably solid and entertaining. The second was hugely disappointing and actually fairly boring.
As for Allegiant, I think they've somewhat rescued the franchise with this film. It answered a lot of questions and moved the story on. We find out the truth about what a Divergent actually is and the truth about what is the other side of the wall. There is some good action in the movie and it's still feels very much a twilight, hunger games style teen movie. The acting is fairly average for what you would expect.
The overriding feeling I got though is how on earth have they got 4 movies out of this franchise? We haven't come a long way in the story so far yet we've sat through 6 hours of movie time. I don't therefore have high hopes for the 4th and (hopefully) final installment. Large sections of all 3 movies could have been cut out and merged and we could have seen 2 really good 2 hours movies. Instead it will go down as another disappointing franchise spread needlessly over 4 movies. Money...
