The first book Divergent is a really good read. Then, I read the second and third books Insurgant and Alliegant and I was like "what happened here?" The second and third books are full of plot holes and are basically the characters reflecting on what happens in Divergent. I don't think they can really be compared because other than having a strong female protagonist, I felt like Hunger Games was such a unique concept, and very thought provoking. Divergent is not. Also, I root for Katniss. I don't really like Tris in Divergent (very headstrong, but no in a good way. Very whiney in Insurgant).
