"Beatrice Prior must confront her inner demons and continue her fight against a powerful alliance which threatens to tear her society apart with the help from others on her side."
Confession time: I haven't read the book in like... a year maybe? So this might not really be an accurate judge of book vs. movie... but moving on!
By itself, I thought this was a really well done movie. The plot was much more exciting and action packed although there is the trade off of a little less romance. The special effects were especially on point.
They did change a bit in the transition between book and movie although I think it was mostly just to streamline the plot. It does make me wonder if they'll change the ending of Allegiant though just to please the audience...?
The cast was also very well done and I thought pretty much all of the characters were played very well. I say mostly because I do think that Naomi Watts looked a bit too young for her part (she played Tobias' mother, Evelyn). Ansel Elgort did a fabulous job of portraying Caleb and he and Shailene (after starring in The Fault In Our Stars together) did a wonderful job adapting to new character dynamics.
The Final Verdict:
This was definitely a very well done movie and if I'd seen it without reading the book, I'd be completely wowed. As it stands, I do wish they hadn't missed some of the key details in the book although I recognize why they had to skip them. I do like the movie much more than the book because the book suffered from typical middle book syndrome meaning that it's just the filler (totally my opinion). The casting was marvelous for the most part and the special effects blew my mind.
