First: (view spoiler)[Dammit, Finnick died. I liked him. (hide spoiler)] 
 I liked the ending, but also didn't exactly like it the first time I read through it. (I admit to hurrying because of something else I had to do tonight. That was part of it.) The rest of this is all spoilery. 
 (view spoiler)[ 
 At first I thought the ending with Gale was a bit of a cop-out, that she never sought him out at all after the trial was over, or tried to speak or be friends again that we know of. On rereading the end, I'm better with it. I understand better that she'll never get over the pain of wondering about the bomb and Prim and how much of a part Gale had in that. I'd like to think that wouldn't entirely kill a friendship, but yeah. I was actually rooting for Gale. (I considered him the underdog of the two guys, honestly.) The author did a very credible job of getting me to buy into Gale not being the right guy for her, though. 
 (I'm probably the only person wondering what the hell they did for birth control for all those years, but then I'm a perv like that. =P ) 
 I loved Katniss's and Finnick's reaction to the Holo displaying all the pods. That scene was priceless. 
 I'm so glad Katniss took out Coin. I wish Boggs had been alive to give his opinion on the matter, honestly. (hide spoiler)] 
 Anyway, not the happiest of book series, but definitely one of the best I've read this year.
