So, I probably should have seen Divergent (2014) first, but this film definitely holds up as a stand alone film as well as part of a trilogy (albeit in four parts).
In a dystopian future, a community is split in to groups based on personality types. But Tris (Shailene Woodley) is different. Together with Four (Theo James) and co., they must fight against the tyranny of Jeanine’s (Kate Winslet) regime.
Although this does sound like every other teen Sci Fi, it stands out for its 3D characters, emotional gravitas (they have sex and it’s not a big deal!) and genuine suspense.
