I love this series, and 1 and 2 were amazing, but this book was a HUGE disappointment. Many deaths were unnecessary and Collins handled Katniss's reactions very poorly. She seemed more sad when Boggs died than when Prim did! For Prim she's like, "Oh. Gale and Coin killed her. Darn." Then she goes more insane. For Boggs, she's like, "NO! ICK! Blood! Boggs, speak to me! Give me instruction for this machine thing! Don't go!" And, worst of all for Finnick, she's just, "I said, 'Nightlock, nightlock, nightlock,' through choked sobs. Poor Finnick. Let's go."
Katniss was a jumbled mess, and she wasn't even present during important events, like her trial. She was OOC (read: out of character) and all mentally disoriented. Yes, her reaction was realistic from pain and everything, but Collins should have changed it so she didn't need to be all weak and pale and angry most of the time. We wanted to see the real Katniss, the brave, valiant one! The plot was dry compared to HG1 and HG2 in comparison. Sure, cool twists, but it didn't meet my expectations. Also, finding her love triangle too tangled to untwine, Collins put Katniss with Peeta by relating Gale to Prim's death. I was a big fan of Katniss/Gale, and was really disappointed that it didn't end up that way, but it would've been tolerable if she had forgiven Gale and kept contact with him. The ending is maddeningly vague and is basically: the war ends with Coin and Snow gone, her best friend since forever just vanishes off the face of the Earth, she gets knocked up by Peeta for real, has kids, doesn't have any visible affection for them, and is still not happy. Her message is, "Ah well, life sucks and then you die, but it used to be worse so might as well try to be happy." WTF??
Anyway, I'm surprised at this website, because the sexual items in this series are big and not even mentioned in the reviews for HG and CF. In CF, Johanna is publicly oiling her-*coughcough* and is stark naked. There are mentions of Cray luring hungry young prostitutes during wintertime, and of course the kissing between Katniss, Gale, and Peeta. Not to mention in CF Peeta has gotten Katniss "pregnant". (They're 16 for God's freaking sake!) "Sex symbol" is used to describe finnick at the beginning of the book 3, and there was Katniss and her alterations way back in Book 1 (padding).
Anyway, I'm disappointed in Mockingjay, but it is one of my favorite series nonetheless. You should finish, but brace yourself for disappointments in 3. Oh yeah, and get ready for a lot of gory violence, it's teeming with that. (Action too, no worries!) Get ready for some tearjerking deaths as well.
