I am a keen upholder of the ‘read the book before you see the film’ motto, however for this particular case I was unable to. Anyway, I’ve seen Divergent. Fell in love with it, read all three books in three days and then saw the film again.
I’m not intentionally going to give away the major plot developments, but if you don’t want to know anything… SPOILER ALERT.
The film, similarly to Hunger Games, managed to immerse me into this believable dystopia that I simultaneously do and do not want to be a part of. Four aka Tobias (played by Theo James), despite being older than intended, managed to play the intimidated trainer and conflicted, scared young adult fantastically, and the romance between him and Tris was slowly built.
If you enjoy a blend of action, crime, romance, dystopia, sci-fi (futuristically), you will love this series. I heartily recommend it.
