I actually didn't think this was a bad book, except for the last third or so.
The first two-thirds held a lot of promise, with the whole psychological/morale war going on between the districts and the Capitol. Some of the action sequences were really contrived (an arrow taking out a hovercraft? really?), but for the PR war promised to be the most compelling part of the series.
Then, they get to the pods. Really? C'mon! What idiot scatters lethal pods throughout an entire urban center? (not to mention releasing killer mutations that don't care which side they kill first) I can usually suspend disbelief for "futuristic" situations (I'm a huge fan of sci-fi), but I can't suspend disbelief over supposed evil geniuses and chess masters
making dumb moves.
Toward the end, though, it really seemed like Suzanne Collins ceased to care about any of her characters by that point in the book. It felt a little odd that she built up a few characters like Finnick just to kill them off with little to no ceremony about their deaths. By the time Prim dies, you're just numb and don't care anymore, because obviously the author doesn't care either! Talk about keeping it real
... real meaningless!
There were some interesting twists, but the Hollywood Tactics
used in the urban warfare were a little ridiculous and the deaths (not a spoiler, people!) were over-the-top and pointless. Honestly, if the trilogy had ended at 2 books, it would have felt as complete.
On the whole, I'm glad I read it, if only to be in-the-know with pop culture, but it's not something I'm going be like, "That trilogy was so awesome! I'm going to read it again in a year."
