Well, after watching movies for more than 25 years, I have never seen anything like this before. Indeed, it happens very often that a franchise gets cancelled after the first installment, it might also happen after the first sequel, but it is the first time ever that I see a franchise getting cancelled before releasing the very last installment. But that's what happened with this franchise and, even though the whole thing was never anything really amazing, it kinda of sucks that we will never get any kind of closure, especially after taking the time and trouble to watch 3 movies. Anyway, coming back to the movie itself, I have to admit that it was indeed pretty weak though. I mean, after going through all this trouble, Tris basically ends up in another dystopian world (how original...) with another bad guy running the show. What was also frustrating was it took her so long to figure this out when it was just so obvious from the very beginning. As a result, Four was actually more interesting this time around and the movie focused a lot on him. Still, it was a step down from the already weak previous installments and it shows that this annoying gimmick of splitting the last book in a trilogy into 2 movies still doesn't work. Anyway, to conclude, I feel bad for Shailene Woodley who is one of the most interesting actress of her generation as she really wasted her time with this franchise and I don't think this final installment is really worth a look.
