Everything I said about The Hunger games holds true for Catching Fire as well, perhaps even more so. Except the part about the snappy pace. In short, it doesn't build on the foundation of Hunger Games, but instead coasts along on HG's efforts. Actually, it was rather forgettable, as many middle books in trilogies are. It's important for me to remember this is YA fiction, and shouldn't be held to the same standards of sex and violence I usually read.
I'm knocking a star off of each of the books in this series. In retrospect, there's nothing in these books that stick with me. No interesting ideas or turns of phrase that warrant the effort of retention for repeating in front of a different audience to make me sound more intelligent than I really am. The best conversation I got out of these was with my wife, "The best way to enjoy the series is to stop after you finish the first one."
