*Updated with movie reaction* 
 THIS IS A HUGE CLIFFHANGER. I have to wait for a year for the last book. Can't wait for it!! 
 Though it's not as good as Divergent, just a few points and I was expecting too much.. Still it's action packed, intense,entertaining and surprising. I feel sad on some parts.. (view spoiler)[ Some characters died and I'm not expecting those characters to die. (hide spoiler)] 
 Tris and Four's love story is just... :"> <3 <3 <3 I JUST LOVE IT! Thumbs up for Ms. Roth! 
 Movie reaction: 
 There are some changes on the scenes, somehow the story is still faithful to the book. Maybe some enhancements so that it will be more entertaining and I love the special effects. I am indeed satisfied with the additional scenes (view spoiler)[there is this one scene where Tris surrendered herself to Erudite compound and we get to see Four's point of view when Tris left him. that wasn't in the book of course but I enjoyed it. I also enjoyed the simulation thing to unlock that mysterious box (in the book it's just a CD , a message from Edith Prior) and I love how they go on character depths. Particularly on Peter and Caleb. (hide spoiler)] 
 Is it just me, but the way Caleb runs is just hilarious. :)) I seriously laughed so hard that the person beside me looked at me like I'm some crazy woman.
