If you have the patience, read on.
If you're a fan, you will enjoy this.
If you have not read the book yet, forego reading this review unless you really want to know where the smoke comes from.
There are SPOILERS so don't say I did not warn you.

What worked
Changes. Challenges. Choices. These are themes that surround Catching Fire and its predecessor, The Hunger Games that readers can flesh out, put back and break down again and again. This is the beauty of HG and CF. It lends new insights, perspectives and possibilities to readers of all ages. Best of all, it opens readers to the complicated nature of the human spirit. Collins may have not consciously intended the books to be an avenue where one can profoundly examine the complexities of the human heart and mind, but I, at least, could not help but delve into the motivations of the book's characters and the reasons for their decisions. I even came to a point when I had to imagine myself in the shoes of her characters, some are flat, predictable and stereotypical. There are, however, characters in the round who transform and grow as the novel unfolds.

Apart from Rue, Johanna Mason and Mags, Finnick's eighty year old mentor, are the female characters I admire. Mrs. Everdeen and Prim are accessories to highlight Katniss's strengths and weaknesses. They also contribute to the plausibility of Katniss' reason for being. She became a hunter to feed them. She learned mistrust when her mother withdrew from the reality of her father's death. Her relationship with Prim tethers her to the concept of family. And it is this connection that she holds on so dearly or else, she will lose her sense of self. Finally, I came to understand the girl on fire.
This vulnerability could only lead me to cheer and root for a Peeta-Katniss tandem in book three. But I doubt. In the end, I have a sinking feeling that Gale will win her over from this trilogy's resident nerd. It's unfair. The nerd deserves the girl. Gale's response to the rebellion is more aggressive. Peetah is the active non-violent kind who will exhaust all efforts for negotiations and dialogues. As for the rebellion, this is something Katniss continues to evade unsuccessfully.

2010 seems too far off.
What did not work
The Point of View. I would have wanted to know the mind scape of the other characters.
I'm on my third reading of HG and CF. Call me a fan, but it's the psychological unfolding of each character and their responses to the external environment that keeps me going back to the books. In general, CF, like HG is being enjoyed by readers of all ages. This only goes to show that Collins has written a well crafted novel that does not use sex or the sensual appeal of the undead.
