I wrote a combined review for all three books in this series.
My Thoughts on Divergent: I absolutely fell in love with this book. I loved every minute of it. The last third of the book was so amazing and intense. I couldn't stop reading and I was biting my nails the whole time. I really enjoyed the progression of the romance between the two main characters (Tris and Four). So many books have "insta-love," but I feel like in this book, their relationship is natural and develops over time. (5/5 stars)
My Thoughts on Insurgent: This book picks up right where Divergent left off, which I really liked as I marathoned the whole series back to back. I really enjoyed this book too, but just a smidge less than the first one. My biggest gripe about this book is the interaction between Tris and Four. I feel like neither one trusted the other, and they were both asking the other to do things they were unwilling to do themselves. The plot of the book was excellent. It was extremely exciting and action packed. (4.5/5 stars)
My Thoughts on Allegiant: This was my least favorite of the trilogy. I was a little reluctant to start reading this one as I heard there was an event that happens and I know many people were extremely upset by that. After reading the third book, I now know what the event was, and I understand why people were upset, but I didn't really mind what happened at all and I feel like it makes sense with the story. I didn't like this book because I felt like it was very boring. There wasn't a lot of action in this book compared to the other books and I just feel like it was very bland, especially after having just read the first two books which were nothing but action. (3/5 stars)
OVERALL RATING FOR THIS TRILOGY: 4/5 stars
I haven't seen the movie yet, and I probably won't be seeing it until it comes out on DVD and I can watch it at home, but I am excited to see it and compare it to the first book.
