mockingjay. cause it tested katniss to find out who she really wanted to be with and love for the rest of her life. also cause it was really dramatic*spoiler* because finnick, boggs, prim, and coin(shocker) ddied. and finally it showed that katniss really could help peeta get better by doing the real not real game thing.
Mockingjay, because it is really deep in the sense that the readers get to discover the growing friendship between Katniss and Finnick/Johanna. I also liked all the plot twists, like Coin killing Prim with the parachute bombs. I kind of liked how Prim grew up and became a rebel medic rather than a frail little girl. Also, I enjoyed how Collins illustrated the slip into insanity Katniss had to suffer through. Finally, I'm relieved that Katniss chose Peeta. I. Hate. Gale. TEAM PEETA! ;p
mine was either the first one, or catching fire, because in the first one you get to develop an understanding of the characters and the hunger games in general, and catching fire because i thought it had a really good plot. also, i thought the end of mockingjay seemed very rushed.
Mockinjay, it had the most depth. It had the complicated story, deeper themes, intellectual messages. A lot of people don't like the ending, but I think it's great. Quite a bittersweet ending, but I loved it! It was darker, sadder, and more violent though.
