This movie is a Hunger Games wannabe, but nowhere near as good despite being similarly rated on imdb. It's OK but the plot doesn't really hold water. In a post apocalyptic future society is divided into the five groups/factions/personaliy types seen in the poster above, and if you don't fit in you are factionless and have to rummage around in bins for your daily bread. That's the first big problem for me as the sum of these five groups can't possibly form a complete functioning society.
Ignoring all of that there is a story to follow and this is a good enough watch if you don't have anything better to do. The way factions are chosen and what happens the new initiates is pretty good. There is a pivotal event, which you can see coming, up to which I was quite enjoying developments. At this point, perhaps due to my age or maybe it was past my bed time, I reached the limits of my attention span and my brain switched off and I coasted through the rest of the movie. Some good fighting scenes and some good baddies along the way.
I haven't done a great job selling this so if you see it you might enjoy it a lot better than you thought you would . If Hunger Games is about an 8 then Divergent is about a 6.5 for me.
